Description: 〈b〉Validating improved-MODIS products from spectral mixture-Landsat snow cover maps in a mountain region in southern Spain〈/b〉〈br〉 Rafael Pimentel, Carlo Marín, Ludovica De Gregorio, Mattia Callegari, María J. Pérez-Palazón, Claudia Notarnicola, and María J. Polo〈br〉 Proc. IAHS, 380, 67-72, https://doi.org/10.5194/piahs-380-67-2018, 2018〈br〉 In Mediterranean regions, the spatiotemporal evolution of the snow cover can experiment quick changes and high frequency sensors are required to adequately monitor such shifts. This work presents a methodological approach to validate the improved MODIS daily snow cover maps, in a Sierra Nevada (southern Spain), from a reference data set obtained by Landsat TM data. The results show a significantly high correlation between the two snow map products at differents spatial scale.

Description: 〈b〉Image acquisition effects on Unmanned Air Vehicle snow depth retrievals〈/b〉〈br〉 Ahmet Emre Tekeli and Senayi Dönmez〈br〉 Proc. IAHS, 380, 81-85, https://doi.org/10.5194/piahs-380-81-2018, 2018〈br〉 Current study is unique in that the SD retrievals were derived using two different image acquisition modes. In the first, images were taken as UAV was continuously flying and in the second UAV kept its position in air fixed as the photos were taken. Root mean square error of derived SDs is found as 2.43 and 1.79 cm in continuous and fixed acquisitions. The results support the hypothesis, that fixed-position image acquisitions using multi-rotor platforms should enable more accurate SD estimates.

Description: 〈b〉Preface: Earth Observation for Integrated Water and Basin Management: Challenges for adaptation to a changing environment〈/b〉〈br〉 María J. Polo, Maria P. González-Dugo, and Christopher Neale〈br〉 Proc. IAHS, 380, 1-2, https://doi.org/10.5194/piahs-380-1-2018, 2018〈br〉

Description: 〈b〉Remote sensing vegetation index methods to evaluate changes in greenness and evapotranspiration in riparian vegetation in response to the Minute 319 environmental pulse flow to Mexico〈/b〉〈br〉 Pamela L. Nagler, Christopher J. Jarchow, and Edward P. Glenn〈br〉 Proc. IAHS, 380, 45-54, https://doi.org/10.5194/piahs-380-45-2018, 2018〈br〉 Our study examined the effects of water transfer, or ecological environmental flows, from one country to another. We studied the impact of a historic, binational, water release, Minute 319 of the 1944 Water Treaty, on vegetative response along the riparian corridor on the lower Colorado River to Mexico. During the spring of 2014, 130 million cubic meters of water were released from the United States to Mexico, allowing water to reach the Gulf of California for the first time in 13 years.

Description: 〈b〉Effect of the water stress on gross primary production modeling of a Mediterranean oak savanna ecosystem〈/b〉〈br〉 Pedro J. Gómez-Giráldez, Elisabet Carpintero, Mario Ramos, Cristina Aguilar, and María P. González-Dugo〈br〉 Proc. IAHS, 380, 37-43, https://doi.org/10.5194/piahs-380-37-2018, 2018〈br〉 This work investigates the effect of different parameterizations to account for water stress on GPP estimates and their agreement with observations. GPP is estimated with a LUE-model in the footprint of the EC tower using several approaches. The preliminary results obtained during two hydrological years (2015/2016 and 2016/2017) are compared, focusing on specific wet and dry periods.

Description: 〈b〉Use of Sentinel 2 – MSI for water quality monitoring at Alqueva reservoir, Portugal〈/b〉〈br〉 Miguel Potes, Gonçalo Rodrigues, Alexandra Marchã Penha, Maria Helena Novais, Maria João Costa, Rui Salgado, and Maria Manuela Morais〈br〉 Proc. IAHS, 380, 73-79, https://doi.org/10.5194/piahs-380-73-2018, 2018〈br〉 The Alqueva reservoir is located in the southeast of Portugal. This region is facing an increase in droughts and a degradation in water quality mainly due to more frequent and lasting phytoplancton blooms. With satellite remote sensing is possible to monitoring such reservoirs. In this study, Sentinel-2 presents very good estimation for chlorophyll a, cyanobacteria and water turbidity during a micro algae bloom that vanished due to the approximation of hurricane Ophelia to Iberian Peninsula.

Description: 〈b〉Evapotranspiration and evaporation/transpiration partitioning with dual source energy balance models in agricultural lands〈/b〉〈br〉 Gilles Boulet, Emilie Delogu, Sameh Saadi, Wafa Chebbi, Albert Olioso, Bernard Mougenot, Pascal Fanise, Zohra Lili-Chabaane, and Jean-Pierre Lagouarde〈br〉 Proc. IAHS, 380, 17-22, https://doi.org/10.5194/piahs-380-17-2018, 2018〈br〉 Mapping of transpiration T and evaporation E is crucial for assessing plant water use and plant water status at landscape scale. Dual-source energy balance models forced by thermal infrared observations provide separate estimates of E and T but rely on specific assumptions to get both terms from the sole surface temperature. We show here with a synthetic experiment that additional information is thus required, e.g. surface water content that can be derived from radar.

Description: 〈b〉Assessment of SMADI and SWDI agricultural drought indices using remotely sensed root zone soil moisture〈/b〉〈br〉 Miriam Pablos, Ángel González-Zamora, Nilda Sánchez, and José Martínez-Fernández〈br〉 Proc. IAHS, 380, 55-66, https://doi.org/10.5194/piahs-380-55-2018, 2018〈br〉 〈p〉The increasing frequency of drought events has expanded the research interest in drought monitoring. In this regard, remote sensing is a useful tool to globally mapping the agricultural drought. While this type of drought is directly linked to the availability of root zone soil moisture (RZSM) for plants growth, current satellite soil moisture observations only characterize the water content of the surface soil layer (0–5 〈span〉cm〈/span〉). In this study, two soil moisture-based agricultural drought indices were obtained at a weekly rate from June 2010 to December 2016, using RZSM estimations at 1 〈span〉km〈/span〉 from the Soil Moisture and Ocean Salinity (SMOS) satellite, instead of surface soil moisture (SSM). The RZSM was estimated by applying the Soil Water Index (SWI) model to the SMOS SSM. The Soil Moisture Agricultural Drought Index (SMADI) and the Soil Water Deficit Index (SWDI) were assessed over the Castilla y León region (Spain) at 1 〈span〉km〈/span〉 spatial resolution. They were compared with the Atmospheric Water Deficit (AWD) and the Crop Moisture Index (CMI), both computed at different weather stations distributed over the study area. The level of agreement was analyzed through statistical correlation. Results showed that the use of RZSM does not influence the characterization of drought, both for SMADI and SWDI.〈/p〉

Description: 〈b〉Use of canopy coefficients obtained from satellite data to estimate evapotranspiration over high mountain Mediterranean watersheds〈/b〉〈br〉 Elisabet Carpintero, María P. González-Dugo, Jorge Jódar, and Sergio Martos-Rosillo〈br〉 Proc. IAHS, 380, 23-28, https://doi.org/10.5194/piahs-380-23-2018, 2018〈br〉 This work monitors the water consumed by the vegetation in two watersheds of Southern Spain for two years. An approach based on the reference evapotranspiration (ETo) and vegetation indices (VIs)-derived canopy coefficients is used (VI-ETo approach). A spatial analysis of ET of the main vegetation types was performed. The annual runoff, estimated with a simple water balance and using the ET, was similar to that obtained by the HBV model, which reproduces the river discharge at the outlet.

Description: 〈b〉Monitoring environmental supporting conditions of a raised bog using remote sensing techniques〈/b〉〈br〉 Saheba Bhatnagar, Bidisha Ghosh, Shane Regan, Owen Naughton, Paul Johnston, and Laurence Gill〈br〉 Proc. IAHS, 380, 9-15, https://doi.org/10.5194/piahs-380-9-2018, 2018〈br〉 〈p〉Conventional methods of monitoring wetlands and detecting changes over time can be time-consuming and costly. Inaccessibility and remoteness of many wetlands is also a limiting factor. Hence, there is a growing recognition of remote sensing techniques as a viable and cost-effective alternative to field-based ecosystem monitoring. Wetlands encompass a diverse array of habitats, for example, fens, bogs, marshes, and swamps. In this study, we concentrate on a natural wetland – Clara Bog, Co. Offaly, a raised bog situated in the Irish midlands. The aim of the study is to identify and monitor the environmental conditions of the bog using remote sensing techniques. Environmental conditions in this study refer to the vegetation composition of the bog and whether it is in an intact (peat-forming) or degraded state. It can be described using vegetation, the presence of water (soil moisture) and topography. Vegetation indices (VIs) derived from satellite data have been widely used to assess variations in properties of vegetation. This study uses mid-resolution data from Sentinel-2 MSI, Landsat 8 OLI for VI analysis. An initial study to delineate the boundary of the bog using the combination of edge detection and segmentation techniques namely, entropy filtering, canny edge detection, and graph-cut segmentation is performed. Once the bog boundary is defined, spectra of the delineated area are studied. VIs like NDVI, ARVI, SAVI, NDWI, derived using Sentinel-2 MSI and Landsat 8 OLI are analysed. A digital elevation model (DEM) was also used for better classification. All of these characteristics (features) serve as a basis for classifying the bog into broad vegetation communities (termed 〈q〉ecotopes〈/q〉) that indicate the quality of raised bog habitat. This analysis is validated using field derived ecotopes. The results show that, by using spectral information and vegetation index clustering, an additional linkage can be established between spectral RS signatures and wetland ecotopes. Hence, the benefit of the study is in understanding ecosystem (bog) environmental conditions and in defining appropriate metrics by which changes in the conditions can be monitored.〈/p〉

Description: 〈b〉Remote sensing-based soil water balance for irrigation water accounting at the Spanish Iberian Peninsula〈/b〉〈br〉 Jesús Garrido-Rubio, Alfonso Calera Belmonte, Lorena Fraile Enguita, Irene Arellano Alcázar, Mario Belmonte Mancebo, Isidro Campos Rodríguez, and Raquel Bravo Rubio〈br〉 Proc. IAHS, 380, 29-35, https://doi.org/10.5194/piahs-380-29-2018, 2018〈br〉 The temporal series of thematically cartography about irrigated areas and corresponding irrigation water requirements based on remote sensing, is a recognized tool to water governance at different scales. Main products generated for the Spanish mainland, 2014–2017, using a multisensor constellation of Landsat 8 and Sentinel-2 satellites are: annual maps of irrigated crops and; monthly and annual maps of remote sensing-based irrigation water accounting by a remote sensing-based soil water balance

Description: 〈b〉Centralized versus distributed reservoirs: an investigation of their implications on environmental flows and sustainable water resources management〈/b〉〈br〉 Nishadi Eriyagama, Vladimir Smakhtin, and Lakshika Udamulla〈br〉 Proc. IAHS, 379, 43-47, https://doi.org/10.5194/piahs-379-43-2018, 2018〈br〉 Creation of surface storage often endanger the functions of natural ecosystems and ecosystem services. The issues of optimal size, placement and the number of reservoirs in a river basin, which maximizes sustainable benefits, while minimizing negative impacts on ecosystems remain subjects for debate. This study examines the above issues through the analysis of a range of reservoir configurations and environmental flow release scenarios in the Malwatu Oya river basin in Sri Lanka.

Description: 〈b〉Application of remote sensing data for measuring freshwater ecosystems changes below the Zeya dam in the Russian Far East〈/b〉〈br〉 Oxana I. Nikitina, Kirill Y. Bazarov, and Evgeny G. Egidarev〈br〉 Proc. IAHS, 379, 49-53, https://doi.org/10.5194/piahs-379-49-2018, 2018〈br〉 Large dams cause extensive environmental impacts. The Zeya hydropower dam is located on the left-bank tributary of the Amur-Heilong, one of the ten largest rivers on Earth. The territory affected by the Zeya dam comprises biodiverse areas. An estimation of the transformation of the freshwater ecosystems is required to develop measures necessary either to maintain or restore disrupted ecosystems. Application of remote sensing methods allows measuring characteristics of the ecosystem's components.

Description: 〈b〉Village-level supply reliability of surface water irrigation in rural China: effects of climate change〈/b〉〈br〉 Yanrong Li and Jinxia Wang〈br〉 Proc. IAHS, 379, 89-104, https://doi.org/10.5194/piahs-379-89-2018, 2018〈br〉 Econometric results revealed that temperature is negatively related with the supply reliability of surface water irrigation; but precipitation positively influences the supply reliability of surface water irrigation. For instance, increasing temperature by 0.5 °C will reduce the supply reliability of surface water irrigation by 1.1 %. When precipitation increases by 10 %, the supply reliability can be increased by 4.6 %. Besides, climate influence differs by seasons.

Description: 〈b〉An assessment of temporal effect on extreme rainfall estimates〈/b〉〈br〉 Samiran Das, Dehua Zhu, and Cheng Chi-Han〈br〉 Proc. IAHS, 379, 145-150, https://doi.org/10.5194/piahs-379-145-2018, 2018〈br〉 This study assesses the temporal behaviour in terms of inter-decadal variability of extreme daily rainfall of stated return period relevant for hydrologic risk analysis using a novel regional parametric approach. The assessment is carried out based on annual maximum daily rainfall series of 180 meteorological stations of Yangtze River Basin over a 50-year period (1961–2010). The outcomes of the analysis reveal that while there were effects present indicating higher quantile values when estimated from data of the 1990s, it is found not to be noteworthy to exclude the data of any decade from the extreme rainfall estimation process for hydrologic risk analysis.

Description: 〈b〉Analysis of vegetation condition and its relationship with meteorological variables in the Yarlung Zangbo River Basin of China〈/b〉〈br〉 Xianming Han, Depeng Zuo, Zongxue Xu, Siyang Cai, and Xiaoxi Gao〈br〉 Proc. IAHS, 379, 105-112, https://doi.org/10.5194/piahs-379-105-2018, 2018〈br〉 To further protect the ecology of the study area, remote sensing image technology is used to analyze the temporal and spatial distribution characteristics of vegetation in the Yarlung Zangbo River Basin by splicing the remote sensing image of a time series (from February 2000 to December 2016). It can be found that vegetation coverage is better in low elevation areas,vegetation change shows a weak sustainability and the vegetation growth is more affected by the temperature than the precipitation.

Description: 〈b〉Impact of urbanization on flood of Shigu creek in Dongguan city〈/b〉〈br〉 Luying Pan, Yangbo Chen, and Tao Zhang〈br〉 Proc. IAHS, 379, 55-60, https://doi.org/10.5194/piahs-379-55-2018, 2018〈br〉 Due to rapid urbanization, quick flood response has been observed in Shigu creek, which posted great threat to the flood security. In this paper, the Land cover/use changes of Shigu creek from 1987–2015 induced by urbanization was extracted and the Liuxihe Model was employed to simulate the flood processes impacted by urbanization. Precipitation of 3 storms was used for flood processes simulation. The results show that the runoff coefficient and peak flow have increased sharply.

Description: 〈b〉Spatiotemporal variability and assessment of drought in the Wei River basin of China〈/b〉〈br〉 Siyang Cai, Depeng Zuo, Zongxue Xu, Xianming Han, and Xiaoxi Gao〈br〉 Proc. IAHS, 379, 73-82, https://doi.org/10.5194/piahs-379-73-2018, 2018〈br〉 Drought is a natural and recurring feature of climate; occurring in virtually all climatic regimes. Wei River is of great importance in social and economic in China. The temporal and spatial variations of drought in the Wei River basin were investigated by calculating the drought indexes. Through analysis of the historical precipitation and temperature data, it was found that precipitation had a greater contribution to creating agricultural drought conditions than temperature.

Description: 〈b〉Assessment of freshwater ecosystem services in the Beas River Basin, Himalayas region, India〈/b〉〈br〉 Sikhululekile Ncube, Lindsay Beevers, Adebayo J. Adeloye, and Annie Visser〈br〉 Proc. IAHS, 379, 67-72, https://doi.org/10.5194/piahs-379-67-2018, 2018〈br〉 The aim of this study is to understand the impact of flow regulation on supporting ecosystem services in the Beas Basin in India, using macroinvertebrates as an indicator. Findings show that both river flows and macroinvertebrate abundance have decreased overtime in the Beas Basin. Consequently, this could have a detrimental impact on instream supporting ecosystem services delivery. Such an understanding is important in future water resources management in the Beas River Basin.

Description: 〈b〉Hydrological regionalisation based on available hydrological information for runoff prediction at catchment scale〈/b〉〈br〉 Qiaoling Li, Zhijia Li, Yuelong Zhu, Yuanqian Deng, Ke Zhang, and Cheng Yao〈br〉 Proc. IAHS, 379, 13-19, https://doi.org/10.5194/piahs-379-13-2018, 2018〈br〉 Regionalisation provides a way of transferring hydrological information from gauged to ungauged catchments. The past few decades has seen several kinds of regionalisation approaches for catchment classification and runoff predictions. The underlying assumption is that catchments having similar catchment properties are hydrological similar. This requires the appropriate selection of catchment properties, particularly the inclusion of observed hydrological information, to explain the similarity of hydrological behaviour. We selected observable catchments properties and flow duration curves to reflect the hydrological behaviour, and to regionalize rainfall-runoff response for runoff prediction. As a case study, we investigated 15 catchments located in the Yangtze and Yellow River under multiple hydro-climatic conditions. A clustering scheme was developed to separate the catchments into 4 homogeneous regions by employing catchment properties including hydro-climatic attributes, topographic attributes and land cover etc. We utilized daily flow duration curves as the indicator of hydrological response and interpreted hydrological similarity by root mean square errors. The combined analysis of similarity in catchment properties and hydrological response suggested that catchments in the same homogenous region were hydrological similar. A further validation was conducted by establishing a rainfall-runoff coaxial correlation diagram for each catchment. A common coaxial correlation diagram was generated for each homogenous region. The performances of most coaxial correlation diagrams met the national standard. The coaxial correlation diagram can be transferred within the homogeneous region for runoff prediction in ungauged catchments at an hourly time scale.

Description: 〈b〉Development of an integrated model for the Campaspe catchment: a tool to help improve understanding of the interaction between society, policy, farming decision, ecology, hydrology and climate〈/b〉〈br〉 Takuya Iwanaga, Fateme Zare, Barry Croke, Baihua Fu, Wendy Merritt, Daniel Partington, Jenifer Ticehurst, and Anthony Jakeman〈br〉 Proc. IAHS, 379, 1-12, https://doi.org/10.5194/piahs-379-1-2018, 2018〈br〉 Improving management of water resources requires understanding of the natural and human components and drivers that influence the resources, and how these interact. Development of an integrated modelling process can be useful for gaining and sharing understanding of the impact of the interactions. Here we have developed such a modelling process for the Campaspe basin in northern Victoria, Australia. The model has been used to explore the impact of various scenarios on the water resources.

Description: 〈b〉Reservoirs operation and water resources utilization coordination in Hongshuihe basin〈/b〉〈br〉 Chonghao Li, Kaige Chi, Bo Pang, and Hongbin Tang〈br〉 Proc. IAHS, 379, 125-129, https://doi.org/10.5194/piahs-379-125-2018, 2018〈br〉 The reservoirs of cascade hydropower stations in Hongshuihe basin are facing more and more integrated water resources utilization problem. This paper introduces the integrated water demand of cascade reservoirs in Hongshuihe and analyses the impact of various types of integrated water demand on power generation. It provides a technical and management guide and demonstration for cascade reservoirs operation and basin integrated water management.

Description: 〈b〉Climate change impact on streamflow in large-scale river basins: projections and their uncertainties sourced from GCMs and RCP scenarios〈/b〉〈br〉 Olga N. Nasonova, Yeugeniy M. Gusev, Evgeny E. Kovalev, and Georgy V. Ayzel〈br〉 Proc. IAHS, 379, 139-144, https://doi.org/10.5194/piahs-379-139-2018, 2018〈br〉 Projections of climate induced changes in streamflow of 11 large-scale rivers located in five continents were modeled up to 2100 using meteorological projections simulated by five global circulation models (GCMs) for four climatic scenarios. Contribution of different sources of uncertainties into a total uncertainty of river runoff projections was analyzed. It was found that contribution of GCMs into the total uncertainty is, on the average, nearly twice larger than that of climatic scenarios.

Description: 〈b〉Sources and behavior of perchlorate ions (ClO〈sub〉4〈/sub〉〈sup〉−〈/sup〉) in chalk aquifer of Champagne-Ardenne, France: preliminary results〈/b〉〈br〉 Feifei Cao, Jessy Jaunat, Patrick Ollivier, Benjamin Cancès, Xavier Morvan, Daniel Hubé, Alain Devos, Nicolas Devau, Vincent Barbin, and Pierre Pannet〈br〉 Proc. IAHS, 379, 113-117, https://doi.org/10.5194/piahs-379-113-2018, 2018〈br〉 Perchlorate can be a health concern due to its its ability to disrupt the thyroid gland's use of iodine. High perchlorate concentrations have been reported in chalk groundwater of Champagne-Ardennes (France). Water samples at 35 sampling points were analysed in order to determine the sources and behaviors of perchlorate. The preliminary results shows that most of the water samples showing high perchlorate levels were collected near a military camp, representing a potential source of perchlorate.

Description: 〈b〉Understanding the potential sources and environmental impacts of dissolved and suspended organic carbon in the diversified Ramganga River, Ganges Basin, India〈/b〉〈br〉 Mohd Yawar Ali Khan and Fuqiang Tian〈br〉 Proc. IAHS, 379, 61-66, https://doi.org/10.5194/piahs-379-61-2018, 2018〈br〉 This study has been conducted on Ramganga River, a major tributary of Ganges River, India, to observe the spatial variation of DOC, dissolved inorganic carbon (DIC), SOC and suspended inorganic carbon (SIC) in river water. The significant conclusions of this investigation revealed that the river and its tributaries show abundance amount of TSC (SOC and SIC) and TDC (DOC and DIC) both in the upstream and downstream. TDC accounts more in river concentration as compared to TSC.

Description: 〈b〉Effect of reservoir zones and hedging factor dynamism on reservoir adaptive capacity for climate change impacts〈/b〉〈br〉 Adebayo J. Adeloye and Bankaru-Swamy Soundharajan〈br〉 Proc. IAHS, 379, 21-29, https://doi.org/10.5194/piahs-379-21-2018, 2018〈br〉 We assessed the effects of different modes of operating reservoir on its ability to moderate water shortage impacts caused by climate change. The operating rule approach was enhanced by hedging using multiple zones and monthly rationing ratios for curtailment of water release. The results showed that basic hedging with single zone and constant rationing ratio caused significant reduction in water shortage during severe droughts. More complex operation modes produced only modest improvement.

Description: 〈b〉Study on reservoir time-varying design flood of inflow based on Poisson process with time-dependent parameters〈/b〉〈br〉 Jiqing Li, Jing Huang, and Jianchang Li〈br〉 Proc. IAHS, 379, 119-123, https://doi.org/10.5194/piahs-379-119-2018, 2018〈br〉 The time-varying design flood is a dynamic design flood, which considers the shortage of water resources and followed the law of flood evolution in reservoir operation. Compared with the traditional design flood, time-varying design flood can make full use of the measured data, reflect the actual situation of the reservoir and so on. Using time-varying design flood to develop a reservoir operation plan not only ensures reservoir safety but also effectively improves water resource utilization.

Description: 〈b〉Framework for quantifying flow and sediment yield to diagnose and solve the aggradation problem of an ungauged catchment〈/b〉〈br〉 Sagar Kumar Tamang, Wenjun Song, Xing Fang, Jose Vasconcelos, and J. Brian Anderson〈br〉 Proc. IAHS, 379, 131-138, https://doi.org/10.5194/piahs-379-131-2018, 2018〈br〉 The opening of the bridge changed from several feet to a few inches due to sediment deposition. The hydrologic model was used to simulate discharges and then sediment generation from the watershed. The study watershed is ungauged and does not have data for model calibration, therefore, a parameter transfer method is used. Basically, a hydrologic model was developed and calibrated for a nearby watershed with streamflow data, and then model parameters are transferred to the ungauged watershed.

Description: 〈b〉Methodology to explore emergent behaviours of the interactions between water resources and ecosystem under a pluralistic approach〈/b〉〈br〉 Glenda García-Santos, Mariana Madruga de Brito, Britta Höllermann, Linda Taft, Adrian Almoradie, and Mariele Evers〈br〉 Proc. IAHS, 379, 83-87, https://doi.org/10.5194/piahs-379-83-2018, 2018〈br〉 Our study presents the utility of a system dynamics modelling approach for water management and decision-making for the case of a forest ecosystem under risk of wildfires. We use the pluralistic water research concept to explore different scenarios and simulate the emergent behaviour of water interception and net precipitation after a wildfire in a forest ecosystem. Through a case study, we illustrate the applicability of this new methodology.

Description: 〈b〉Understanding the Impacts of Climate Change in the Tana River Basin, Kenya〈/b〉〈br〉 Lal Muthuwatta, Aditya Sood, Matthew McCartney, Nishchitha Sandeepana Silva, and Alfred Opere〈br〉 Proc. IAHS, 379, 37-42, https://doi.org/10.5194/piahs-379-37-2018, 2018〈br〉 In the Tana River Basin in Kenya, six Regional Circulation Models (RCMs) simulating two Representative Concentration Pathways (RCPs) (i.e., 4.5 and 8.5) were used as input to the Soil and Water Assessment Tool (SWAT) model to determine the possible implications for the hydrology and water resources of the basin. Four hydrological characteristics – water yield, groundwater recharge, base flow and flow regulation – were determined and mapped throughout the basin for three 30-year time periods: 2020–2049, 2040–2069 and 2070–2099. Results were compared with a baseline period, 1983–2011. All four hydrological characteristics show steady increases under both RCPs for the entire basin but with considerable spatial heterogeneity and greater increases under RCP 8.5 than RCP 4.5. The results have important implications for the way water resources in the basin are managed. It is imperative that water managers and policy makers take into account the additional challenges imposed by climate change in operating built infrastructure.

Description: 〈b〉Stability and tilting of regional water cycle over Tarim Basin〈/b〉〈br〉 Hongquan Zhang and Zhuguo Ma〈br〉 Proc. IAHS, 379, 31-36, https://doi.org/10.5194/piahs-379-31-2018, 2018〈br〉 The water consumption imbalance in Tarim Basin is caused by human activities and tilts the humidity profile over the basin. As a result, more water vapour spills from the western part of the basin and causes precipitation to increase in adjacent areas. At the same time, the Westerlies carry the low humidity air mass out of the eastern part of the basin to make the downwind Gobi Desert and surrounding areas drier.

Description: 〈b〉Estimating lake-water evaporation from data of large-aperture scintillometer in the Badain Jaran Desert, China, with two comparable methods〈/b〉〈br〉 Peng-Fei Han, Xu-Sheng Wang, Xiaomei Jin, and Bill X. Hu〈br〉 Proc. IAHS, 379, 433-442, https://doi.org/10.5194/piahs-379-433-2018, 2018〈br〉 〈p〉Accurate quantification of evaporation (〈span〉〈i〉E〈/i〉〈sub〉0〈/sub〉〈/span〉) from open water is vital in arid regions for water resource management and planning, especially for lakes in the desert. The scintillometers are increasingly recognized by researchers for their ability to determine sensible (〈span〉〈i〉H〈/i〉〈/span〉) and latent heat fluxes (LE) accurately over distances of hundreds of meters to several kilometers, though scintillometers are mainly used to monitor the land surface processes. In this paper, it is installed on both sides of the shore over a lake. Compared to the data of evaporationpan, the scintillometer was successfully applied to Sumu Barun Jaran in Badain Jaran Desert using the classical method and the proposed linearized 〈span〉〈i〉β〈/i〉〈/span〉 method. Due to the difficulty in measuring water surface temperature and the easiness to monitor the water temperature at different depths, it is worth thinking that if is feasible to utilize the shallow water temperature instead of the water surface temperature and how much errors it will cause. Water temperature at 10 and 20 cm depths were used to replace the lakewater surface temperature in the two methods to analyze the changes of sensible and latent heat fluxes in hot and cold seasons at halfhour time scales. Based on the classical method, the values of 〈span〉〈i〉H〈/i〉〈/span〉 were almost barely affected, and the average value of LE using water temperature at 20 cm depth is 0.8–9.5 % smaller than that at 10 cm depth in cold seasons. In hot seasons, compared to the results at 10 cm depth, the average value of 〈span〉〈i〉H〈/i〉〈/span〉 increased by 20–30 %, and LE decreased by about 20 % at 20 cm depth. In the proposed linearized 〈span〉〈i〉β〈/i〉〈/span〉 method of scintillometer, only the slope of the saturation pressure curve (〈span〉Δ〈/span〉) is related to the water surface temperature, which was estimated using available equations of saturated vapor pressure versus temperature of the air. Compared to the values of estimated by the air temperature, while the water surface temperature are replaced by water temperature at 10 and 20 cm depths, in different seasons, the errors of 2–25 % in 〈span〉Δ〈/span〉 were caused. Thus was calculated by the original equation in the proposed linearized 〈span〉〈i〉β〈/i〉〈/span〉 method of scintillometer. Interestingly, the water temperature at 10 and 20 cm depths had little effect on 〈span〉〈i〉H〈/i〉〈/span〉, LE (〈span〉〈i〉E〈/i〉〈sub〉0〈/sub〉〈/span〉) in different seasons. The reason is that the drying power of the air (〈span〉〈i〉E〈/i〉〈sub〉A〈/sub〉〈/span〉) accounted for about 85 % of the evaporation (i.e. the changes of 〈span〉Δ〈/span〉 have only about 3 % impact on evaporation), which indicated that the driving force from unsaturated to saturated vapor pressure at 2 m height (i.e. the aerodynamic portion) has the main role on evaporation. Therefore, the proposed linearized 〈span〉〈i〉β〈/i〉〈/span〉 method of scintillometer is recommended to quantify the 〈span〉〈i〉H〈/i〉〈/span〉, LE (〈span〉〈i〉E〈/i〉〈sub〉0〈/sub〉〈/span〉) over open water, especially when the water surface temperature cannot be accurately measured.〈/p〉

Description: Long-term monitoring of gully erosion in Udmurt Republic, Russia Ivan Rysin, Ivan Grigoriev, Mariya Zaytseva, Valentin Golosov, and Aidar Sharifullin Proc. IAHS, 375, 1-4, doi:10.5194/piahs-375-1-2017, 2017 This article presents results from the long term-monitoring of gully headcut retreat rates (GHRR) between 1959 and 2015 in different parts of the Udmurt Republic and is based on the use of historical aerial photographs and field observations. It was determined that GHRR decreased from 2.4 to 0.3 m yr −1 during the 1959–1997 observation period and the 1998–2015 period, respectively.

Description: The use of bed sediments in water quality studies and monitoring programs Arthur J. Horowitz and Kent A. Elrick Proc. IAHS, 375, 11-17, doi:10.5194/piahs-375-11-2017, 2017 Bed sediment chemical data are not normally used in traditional water quality monitoring studies/programs. However, they can be quite useful for reconnaissance purposes to identify potential long term monitoring sites and or water quality hotspots as well as to reconstruct long term water quality chemical levels. The paper provides three examples where bed sediments have been used successfully for those purposes.

Description: Modelling suspended sediment distribution in the Selenga River Delta using LandSat data Sergey R. Chalov, Varvara O. Bazilova, and Mikhail K. Tarasov Proc. IAHS, 375, 19-22, doi:10.5194/piahs-375-19-2017, 2017 The Selenga River is the largest tributary of Baikal Lake, it's delta covers around 600 km 2 . Suspended sediment concentrations (SSC) in the Selenga river delta were modelled based on LandSat images data. The variability in suspended sediment retention during the period 1989 to 2015 was calculated. The results suggest that SSC storage in the delta is observed during high discharges, whereas export increases under lower flow conditions. The changes in seasonal patterns are explained by wetland.

Description: The potential for gamma-emitting radionuclides to contribute to an understanding of erosion processes in South Africa Ian D. L. Foster, John Boardman, Adrian L. Collins, Ruth Copeland-Phillips, Nikolaus J. Kuhn, Tim M. Mighall, Simon Pulley, and Kate M. Rowntree Proc. IAHS, 375, 29-34, https://doi.org/10.5194/piahs-375-29-2017, 2017 The paper explores existing data bases relating to erosion and sediment transport in South Africa. It identifies a number of problems with using these and stresses the need to supplement existing data with a novel approach based on the use of sediments accumulating in small farm dams. These could provide directly comparable data by identifying a common time line in all dams using a radioactive fallout isotope called Caesium-137 that was first liberated into the global atmosphere in the 1950s.

Description: Crystal balls into the future: are global circulation and water balance models ready? Balázs M. Fekete, Giovanna Pisacane, and Dominik Wisser Proc. IAHS, 374, 41-51, https://doi.org/10.5194/piahs-374-41-2016, 2016 Variabilities and changes due to natural and anthropogenic causes in the water cycle always presented a challenge for water management planning. Practitioners traditionally coped with variabilities in the hydrological processes by assuming stationarity. Recently, this practice was questioned and more reliance on Global Circulation Models was put forward as an alternative. This paper takes a brief assessment of the state of Global Circulation Models (GCM) and their applications.

Description: Integrated water resource assessment for the Adelaide region, South Australia James W. Cox, Michele Akeroyd, and Danielle P. Oliver Proc. IAHS, 374, 69-73, https://doi.org/10.5194/piahs-374-69-2016, 2016 Water research is one of South Australia's (SA's) highest priorities. Focus on water research became more critical during a drought that occurred between 1997 and 2011. Increased concern about water security for regional communities, industry and the environment led to the SA government establishing the Goyder Institute for Water Research to undertake cutting-edge science to inform the development of innovative integrated water management strategies to ensure SA's ongoing water security.

Description: Developing new scenarios for water allocation negotiations: a case study of the Euphrates River Basin Mohammad Reza Jarkeh, Ameneh Mianabadi, and Hojjat Mianabadi Proc. IAHS, 374, 9-15, https://doi.org/10.5194/piahs-374-9-2016, 2016 In this paper we established a new method to choose the most appropriate allocating rule which seems to be more equitable and reasonable than other allocation rules to satisfy the riparian countries. To evaluate this new proposed method, we applied seven Classical Bankruptcy Rules (CBRs) and four Sequential Sharing Rules (SSRs) in allocating the Euphrates River water among three riparian countries: Turkey, Syria and Iraq.

Description: SMART – Sediment Mitigation Actions for the River Rother, UK Jennine L. Evans, Ian Foster, John Boardman, and Naomi Holmes Proc. IAHS, 375, 35-39, https://doi.org/10.5194/piahs-375-35-2017, 2017 Excess sediment has been identified as a key issue for the River Rother, West Sussex, UK, a 350 km 2 river catchment. The aim is to identify the severity, extent, possible causes and potential mitigation options available to reduce sediment into the river. Ten monitoring sites were installed on four major tributaries and the main channel of the River Rother to collect sediment in the river. Sediment will be compared with possible source soil samples to trace where the sediment originated.

Description: A regional approach to climate adaptation in the Nile Basin Michael B. Butts, Carlo Buontempo, Jens K. Lørup, Karina Williams, Camilla Mathison, Oluf Z. Jessen, Niels D. Riegels, Paul Glennie, Carol McSweeney, Mark Wilson, Richard Jones, and Abdulkarim H. Seid Proc. IAHS, 374, 3-7, https://doi.org/10.5194/piahs-374-3-2016, 2016 The Nile Basin is one of the most important shared basins in Africa. Managing it's water resources, now and in the future, must not only address different water uses but also the trade-off between developments upstream and water use downstream, often between different countries. This paper presents a methodology, to support climate adaptation on a regional scale, for assessing climate change impacts and adaptation potential for floods, droughts and water scarcity within this basin.

Description: Post conflict water management: learning from the past for recovery planning in the Orontes River basin Myriam Saadé-Sbeih, François Zwahlen, Ahmed Haj Asaad, Raoul Gonzalez, and Ronald Jaubert Proc. IAHS, 374, 17-21, https://doi.org/10.5194/piahs-374-17-2016, 2016 Water management is a fundamental issue in post-conflict planning in Syria. Based on historical water balance assessment, this study identifies the drivers of the profound changes that took place in the Lebanese and Syrian parts of the Orontes River basin since the 1930s. Both drastic effects of the conflict on the hydro-system and the strong uncontrolled anthropization of the river basin prior to the crisis have to be considered in the design of recovery interventions.

Description: The new portfolio of global precipitation data products of the Global Precipitation Climatology Centre suitable to assess and quantify the global water cycle and resources Udo Schneider, Markus Ziese, Anja Meyer-Christoffer, Peter Finger, Elke Rustemeier, and Andreas Becker Proc. IAHS, 374, 29-34, https://doi.org/10.5194/piahs-374-29-2016, 2016 The Global Precipitation Climatology Centre (GPCC) operated by Deutscher Wetterdienst since 1989 provides reliable information on monthly and daily precipitatation since 1901 and 1988, respectively. The information is provided as DOI referenced data sets and we provide herewith an overview and orientation which product is most suitable for a number of archetype use cases. We also provide some illustration on particular use cases. The GPCC data product will be further upgraded and prolongued.

Description: Impact of climate change and anthropogenic pressure on the water resources of India: challenges in management K. Shadananan Nair Proc. IAHS, 374, 63-67, https://doi.org/10.5194/piahs-374-63-2016, 2016 The paper assesses the impact of climate change and anthropogenic pressure on the water resources of India and its reflections on different sectors. Changes in water availability in two decades from now under an altered climate have been estimated using hydrological model, based on the projections from climate models. Existing policies and adaptation strategies have been critically reviewed to suggest guidelines for adaptation and mitigation measures in the water sector.

Description: To what extent do they sway Australian water management decision making? Maureen Papas Proc. IAHS, 374, 23-28, https://doi.org/10.5194/piahs-374-23-2016, 2016 The reliability of freshwater resources has become highly unpredictable as consequences of climate change and increasingly frequent droughts. The role of science in decision-making points to the need to constantly improve our capabilities to forecast the availability of seasonal water. While science has a fundamental role to play in effective water resources management, the reality on the ground often diverges from the intended aim and does not always reflect efforts at reform.

Description: Water resources assessment and prediction in China Wang Guangsheng, Dai Ning, Yang Jianqing, and Wang Jinxing Proc. IAHS, 374, 79-84, https://doi.org/10.5194/piahs-374-79-2016, 2016 Water resources assessment in China can be classified as: comprehensive water resources assessment, annual water resources assessment, and industrial project water resources assessment. For the water resources prediction in China usually the monthly runoff prediction is used, in most low flow seasons, the flow recession curve is commonly used, in the humid regions the rainfall-runoff ensemble prediction has been widely applied, the conditional probability method was also applied.

Description: Evaluation of soil erosion rates in the southern half of the Russian Plain: methodology and initial results Valentin Golosov, Artem Gusarov, Leonid Litvin, Oleg Yermolaev, Nelly Chizhikova, Guzel Safina, and Zoya Kiryukhina Proc. IAHS, 375, 23-27, https://doi.org/10.5194/piahs-375-23-2017, 2017 This paper describes the use of erosion model calculations and GIS spatial analytical methods for the evaluation of trends in erosion rates in the RP. Climate change, land use transformation and crop rotation modification are the main factors governing erosion rates in the region during recent decades.

Description: Bedload transport monitoring with acoustic sensors in the Swiss Albula mountain river Dieter Rickenmann, Gilles Antoniazza, Carlos R. Wyss, Bruno Fritschi, and Stefan Boss Proc. IAHS, 375, 5-10, https://doi.org/10.5194/piahs-375-5-2017, 2017 Bedload transport measurements were performed with acoustic sensors (geophones and accelerometers) mounted underneath impact plates during summer 2015 in the Albula River in Switzerland. The measurements showed that the signal response in terms of geophone and accelerometer impulses is comparable for both types of sensors and that there is a good correlation between discharge data and impulses recorded by both types of sensors.

Description: Rainfall as proxy for evapotranspiration predictions Bruno Collischonn and Walter Collischonn Proc. IAHS, 374, 35-40, https://doi.org/10.5194/piahs-374-35-2016, 2016 Hydrometerologial data in Brazil is becoming increasingly more accessible in recent years, but data gaps still exist in many regions. In our work, we tested some statistical ways to explore the existing data and fill gaps in evaporation estimates, based on the assumption that evaporation and precipitation are inversely related. This could be useful for extending evaporation series into the past, for example for hydropower reservoir planning and flow forecast.

Description: Impact of climate forcing uncertainty and human water use on global and continental water balance components Hannes Müller Schmied, Linda Adam, Stephanie Eisner, Gabriel Fink, Martina Flörke, Hyungjun Kim, Taikan Oki, Felix Theodor Portmann, Robert Reinecke, Claudia Riedel, Qi Song, Jing Zhang, and Petra Döll Proc. IAHS, 374, 53-62, https://doi.org/10.5194/piahs-374-53-2016, 2016 We analyzed simulated water balance components on global and continental scale as impacted by the uncertainty of climate forcing datasets. On average, around 62 % of precipitation on global land area evapotranspires and 38 % is discharge to oceans and inland sinks. Human water use increased during the 20th century by a factor of 5. Uncertainty of precipitation variable has most impact on model results, followed by shortwave downward radiation. Model calibration reduces this uncertainty.

Description: Water resources of the Russian rivers and their changes Mikhail Georgievsky Proc. IAHS, 374, 75-77, https://doi.org/10.5194/piahs-374-75-2016, 2016 This paper is a review of the recent investigations related to changes in river water resources of the Russian Federation performed at the State Hydrological Institute (SHI). The long-term water resources fluctuations and their changes during the last decades including the significant changes in seasonal runoff are presented. The preliminary estimates of the possible future changes are also given.

Description: Impact of urbanization on rainfall-runoff processes: case study in the Liangshui River Basin in Beijing, China Zongxue Xu and Gang Zhao Proc. IAHS, 373, 7-12, doi:10.5194/piahs-373-7-2016, 2016 China is undergoing rapid urbanization during the past decades. For example, the proportion of urban population in Beijing has increased from 57.6 % in 1980 to 86.3 % in 2013. Rapid urbanization has an adverse impact on the urban rainfall-runoff processes, which may result in the increase of urban flooding risk. In this study, the major purpose is to investigate the impact of land use/cover changes on hydrological processes and the flooding risk in Beijing.

Description: Managing saltwater intrusion in coastal arid regions and its societal implications for agriculture Jens Grundmann, Ayisha Al-Khatri, and Niels Schütze Proc. IAHS, 373, 31-35, doi:10.5194/piahs-373-31-2016, 2016 Coastal aquifers in arid and semiarid regions are particularly at risk due to intrusion of salty marine water. Since groundwater is predominantly used in irrigated agriculture, its excessive pumping – above the natural rate of replenishment – strengthen the intrusion process. Using this increasingly saline water for irrigation, leads to a destruction of valuable agricultural resources and the economic basis of farmers and their communities. The limitation of resources (water and soil) in these regions requires a societal adaptation and change in behaviour as well as the development of appropriate management strategies for a transition towards stable and sustainable future hydrosystem states. Besides a description of the system dynamics and the spatial consequences of adaptation on the resources availability, the contribution combines results of an empirical survey with stakeholders and physically based modelling of the groundwater-agriculture hydrosystem interactions. This includes an analysis of stakeholders' (farmers and decision makers) behaviour and opinions regarding several management interventions aiming on water demand and water resources management as well as the thinking of decision makers how farmers will behave. In this context, the technical counter measures to manage the saltwater intrusion by simulating different groundwater pumping strategies and scenarios are evaluated from the economic and social point of view and if the spatial variability of the aquifer's hydrogeology is taken into consideration. The study is exemplarily investigated for the south Batinah region in the Sultanate of Oman, which is affected by saltwater intrusion into a coastal aquifer system due to excessive groundwater withdrawal for irrigated agriculture.

Description: Local irrigation systems, regional hydrological problems and the demand for overarching solutions at the example of an irrigation system in the P.R. of China David Nijssen, Andreas H. Schumann, and Bertram Monninkhoff Proc. IAHS, 373, 37-43, doi:10.5194/piahs-373-37-2016, 2016 To objectively compare possible solutions for drought, they have to be commensurable; a daunting condition if they are implementable on dissimilar spatial scales and/or physical compartments. In a water scarce region in China it is it is shown how a generic meta-model in form of a dynamic water balance simulating the hydrosystem, including anthropogenic factors, allows the appraisal of various measure's effects on one one factor; thus securing commensurability.

Description: Reservoir impacts downstream in highly regulated river basins: the Ebro delta and the Guadalquivir estuary in Spain María J. Polo, Albert Rovira, Darío García-Contreras, Eva Contreras, Agustín Millares, Cristina Aguilar, and Miguel A. Losada Proc. IAHS, 373, 45-49, doi:10.5194/piahs-373-45-2016, 2016 Regulation by reservoirs affects both the freshwater regime and the sediment delivery downstream. Spain is one the countries with more water storage capacity by reservoirs in the world. The spatial redistribution of the seasonal and annual water storage in reservoirs mainly for irrigation and urban supply has resulted in significant environmental impacts downstream. This work shows these effects in the Guadalquivir and the Ebro River basins, two of the largest regulated areas in Spain.

Description: Sustainable land and water management of River Oases along the Tarim River Markus Disse Proc. IAHS, 373, 25-29, doi:10.5194/piahs-373-25-2016, 2016 The Tarim Basin in Xinjiang province in northwest China is characterized by a hyper arid climate. Climate change and a strong increase in agricultural land use are major challenges for sustainable water management. The largest competition for water resources exists between irrigated fields and natural riparian vegetation. The Sino-German project SuMaRiO provided a decision support system based on ecosystem services and will implement sustainable water management measures in the next 5-year plan.

Description: A flexible and efficient multi-model framework in support of water management Vincent Wolfs, Quan Tran Quoc, and Patrick Willems Proc. IAHS, 373, 1-6, doi:10.5194/piahs-373-1-2016, 2016 Water management is constantly evolving. Trends, such as population growth, urbanization and climate change, pose new challenges to water management. We developed a new and flexible modelling approach to generate very fast models of catchment hydrology, rivers and sewer systems that can be tailored to numerous applications in water management. To illustrate the developed framework, a case study of integrated hydrological-hydraulic modelling for the Grote Nete catchment in Belgium is elaborated.

Description: Added-value from a multi-criteria selection of donor catchments in the prediction of continuous streamflow series at ungauged pollution control-sites Gilles Drogue, Wiem Ben Khediri, and Céline Conan Proc. IAHS, 373, 69-72, doi:10.5194/piahs-373-69-2016, 2016 River flow series are the essential input of many studies and applications aiming to add value and interpret the water quality data collected at pollution-control sites. They are however available only in a limited number of points on the river network where flows are known. Our paper assess the performance of strategies for simulating incomplete or missing flow series. They rest on the use of a simple hydrological model and the assumption that flows are similar between neighbor catchments.

Description: Spatially-smooth regionalization of flow duration curves in non-pristine basins Daniele Ganora, Francesco Laio, Alessandro Masoero, and Pierluigi Claps Proc. IAHS, 373, 73-80, doi:10.5194/piahs-373-73-2016, 2016 The flow duration curve is a widely used tool to support water resources management, planning of hydropower plants and many other problems in hydrological engineering. This paper describe a procedure to estimate the flow duration curve in river sections where no data are available by exploiting observations from other gauged river basins. The procedure also allows one to include information about existing water intakes that alter the natural flow in the river.

Description: A regional look at the selection of a process-oriented model for flood peak/volume relationships Ján Szolgay, Ladislav Gaál, Tomáš Bacigál, Silvia Kohnová, Kamila Hlavčová, Roman Výleta, and Günter Blöschl Proc. IAHS, 373, 61-67, doi:10.5194/piahs-373-61-2016, 2016 The design of hydraulic structures where storage is involved, requires estimates of joint probability distribution of flood volumes and flood peaks. The problem of choosing a joint distribution was so far approached more from a statistical point of view. In the paper the suitability of various copula models of this relationships was analysed with a particular focus on the type and seasonality of flood generation processes in a regional context.

Description: The value of weather radar data for the estimation of design storms – an analysis for the Hannover region Uwe Haberlandt and Christian Berndt Proc. IAHS, 373, 81-85, doi:10.5194/piahs-373-81-2016, 2016 Pure radar rainfall, station rainfall and radar-station merging products are analysed regarding extreme rainfall frequencies with durations from 5 min to 6 h and return periods from 1 year to 30 years. Partial duration series of the extremes are derived from the data and probability distributions are fitted. The performance of the design rainfall estimates is assessed based on cross validations for observed station points, which are used as reference. For design rainfall estimation using the pure radar data, the pixel value at the station location is taken; for the merging products, spatial interpolation methods are applied. The results show, that pure radar data are not suitable for the estimation of extremes. They usually lead to an overestimation compared to the observations, which is opposite to the usual behaviour of the radar rainfall. The merging products between radar and station data on the other hand lead usually to an underestimation. They can only outperform the station observations for longer durations. The main problem for a good estimation of extremes seems to be the poor radar data quality.

Description: Scaling issues in multi-criteria evaluation of combinations of measures for integrated river basin management Jörg Dietrich Proc. IAHS, 373, 19-24, doi:10.5194/piahs-373-19-2016, 2016 This research article presents finding from an interdisciplinary joint research project in integrated river basin management. For the implementation of the EU Water Framework Directive, measures to improve the hydromorphological situation and to reduce nutrient emissions have been planned at water body scale. We used a strategy approach to formulate alternative solutions for the whole basin according to policy directions. The results should inform and support stakeholders and decision makers.

Description: Modeling human-water-systems: towards a comprehensive and spatially distributed assessment of co-evolutions for river basins in Central Europe Peter Krahe, Enno Nilson, Malte Knoche, and Anna-Dorothea Ebner von Eschenbach Proc. IAHS, 373, 119-123, doi:10.5194/piahs-373-119-2016, 2016 In the context of medium to long term river basin and flood risk management there is a growing need to improve the understanding of and the feedbacks between the driving forces "climate and socio-economy" and water systems, e.g. by combining scenarios of the global and regional climate change with those of developments of the society.

Description: Spatial variability of the parameters of a semi-distributed hydrological model Alban de Lavenne, Guillaume Thirel, Vazken Andréassian, Charles Perrin, and Maria-Helena Ramos Proc. IAHS, 373, 87-94, doi:10.5194/piahs-373-87-2016, 2016 Developing modelling tools that help to understand the spatial distribution of water resources is a key issue for better management. Ideally, hydrological models which discretise catchment space into sub-catchments should offer better streamflow simulations than lumped models, along with spatially-relevant water resources management solutions. However we demonstrate that those model raise other issues related to the calibration strategy and to the identifiability of the parameters.

Description: Climate, orography and scale controls on flood frequency in Triveneto (Italy) Simone Persiano, Attilio Castellarin, Jose Luis Salinas, Alessio Domeneghetti, and Armando Brath Proc. IAHS, 373, 95-100, doi:10.5194/piahs-373-95-2016, 2016 The growing concern about the possible effects of climate change on flood frequency regime is leading Authorities to review reference procedures for design flood estimation. Our study focuses on Triveneto (Italy) and proposes an update of the existing reference procedure by properly considering climate and scale controls on flood frequency. Moreover, the study highlights the remarkable influence of a single extreme-floods year on analyses for detecting possible changes in flood frequency regime.

Description: Impact of climate forcing uncertainty and human water use on global and continental water balance components Hannes Müller Schmied, Linda Adam, Stephanie Eisner, Gabriel Fink, Martina Flörke, Hyungjun Kim, Taikan Oki, Felix Theodor Portmann, Robert Reinecke, Claudia Riedel, Qi Song, Jing Zhang, and Petra Döll Proc. IAHS, 374, 53-62, doi:10.5194/piahs-374-53-2016, 2016 We analyzed simulated water balance components on global and continental scale as impacted by the uncertainty of climate forcing datasets. On average, around 62 % of precipitation on global land area evapotranspires and 38 % is discharge to oceans and inland sinks. Human water use increased during the 20th century by a factor of 5. Uncertainty of precipitation variable has most impact on model results, followed by shortwave downward radiation. Model calibration reduces this uncertainty.

Description: Post conflict water management: learning from the past for recovery planning in the Orontes River basin Myriam Saadé-Sbeih, François Zwahlen, Ahmed Haj Asaad, Raoul Gonzalez, and Ronald Jaubert Proc. IAHS, 374, 17-21, doi:10.5194/piahs-374-17-2016, 2016 Water management is a fundamental issue in post-conflict planning in Syria. Based on historical water balance assessment, this study identifies the drivers of the profound changes that took place in the Lebanese and Syrian parts of the Orontes River basin since the 1930s. Both drastic effects of the conflict on the hydro-system and the strong uncontrolled anthropization of the river basin prior to the crisis have to be considered in the design of recovery interventions.

Description: Developing new scenarios for water allocation negotiations: a case study of the Euphrates River Basin Mohammad Reza Jarkeh, Ameneh Mianabadi, and Hojjat Mianabadi Proc. IAHS, 374, 9-15, doi:10.5194/piahs-374-9-2016, 2016 In this paper we established a new method to choose the most appropriate allocating rule which seems to be more equitable and reasonable than other allocation rules to satisfy the riparian countries. To evaluate this new proposed method, we applied seven Classical Bankruptcy Rules (CBRs) and four Sequential Sharing Rules (SSRs) in allocating the Euphrates River water among three riparian countries: Turkey, Syria and Iraq.

Description: Crystal balls into the future: are global circulation and water balance models ready? Balázs M. Fekete, Giovanna Pisacane, and Dominik Wisser Proc. IAHS, 374, 41-51, doi:10.5194/piahs-374-41-2016, 2016 Variabilities and changes due to natural and anthropogenic causes in the water cycle always presented a challenge for water management planning. Practitioners traditionally coped with variabilities in the hydrological processes by assuming stationarity. Recently, this practice was questioned and more reliance on Global Circulation Models was put forward as an alternative. This paper takes a brief assessment of the state of Global Circulation Models (GCM) and their applications.

Description: Rainfall as proxy for evapotranspiration predictions Bruno Collischonn and Walter Collischonn Proc. IAHS, 374, 35-40, doi:10.5194/piahs-374-35-2016, 2016 Hydrometerologial data in Brazil is becoming increasingly more accessible in recent years, but data gaps still exist in many regions. In our work, we tested some statistical ways to explore the existing data and fill gaps in evaporation estimates, based on the assumption that evaporation and precipitation are inversely related. This could be useful for extending evaporation series into the past, for example for hydropower reservoir planning and flow forecast.

We also provide some illustration on particular use cases. The GPCC data product will be further upgraded and prolongued.

Description: Water resources of the Russian rivers and their changes Mikhail Georgievsky Proc. IAHS, 374, 75-77, doi:10.5194/piahs-374-75-2016, 2016 This paper is a review of the recent investigations related to changes in river water resources of the Russian Federation performed at the State Hydrological Institute (SHI). The long-term water resources fluctuations and their changes during the last decades including the significant changes in seasonal runoff are presented. The preliminary estimates of the possible future changes are also given.

Description: Development and implementation of a monitoring and information system to increase water use efficiency in arid and semi-arid areas in Limarí, Central Chile (WEIN) Erich Berger, David Balmert, and Jürgen Richter Proc. IAHS, 374, 101-104, doi:10.5194/piahs-374-101-2016, 2016 In the scope of the BMBF funded project "WEIN", an integrated system for analysis, monitoring and information at river basin level was developed, which provides relevant information for all stakeholders that are concerned with water resource issues. The main objective was to improve water use efficiency and hence guarantee a sustainable agricultural production. The pilot region, in which this desktop and web-based system was implemented, is the semi-arid Limarí basin in Northern Central Chile.

Description: Development of seasonal flow outlook model for Ganges-Brahmaputra Basins in Bangladesh Sazzad Hossain, Raihanul Haque Khan, Dilip Kumar Gautum, Ripon Karmaker, and Amirul Hossain Proc. IAHS, 374, 117-121, doi:10.5194/piahs-374-117-2016, 2016 Bangladesh is crisscrossed by the branches and tributaries of three main river systems, the Ganges, Bramaputra and Meghna (GBM). The temporal variation of water availability of those rivers has an impact on the different water usages such as irrigation, urban water supply, hydropower generation, navigation etc. Thus, seasonal flow outlook can play important role in various aspects of water management. The Flood Forecasting and Warning Center (FFWC) in Bangladesh provides short term and medium term flood forecast, and there is a wide demand from end-users about seasonal flow outlook for agricultural purposes. The objective of this study is to develop a seasonal flow outlook model in Bangladesh based on rainfall forecast. It uses European Centre for Medium-Range Weather Forecasts (ECMWF) seasonal precipitation, temperature forecast to simulate HYDROMAD hydrological model. Present study is limited for Ganges and Brahmaputra River Basins. ARIMA correction is applied to correct the model error. The performance of the model is evaluated using coefficient of determination ( R 2 ) and Nash–Sutcliffe Efficiency (NSE). The model result shows good performance with R 2 value of 0.78 and NSE of 0.61 for the Brahmaputra River Basin, and R 2 value of 0.72 and NSE of 0.59 for the Ganges River Basin for the period of May to July 2015. The result of the study indicates strong potential to make seasonal outlook to be operationalized.

Description: Integrated water resource assessment for the Adelaide region, South Australia James W. Cox, Michele Akeroyd, and Danielle P. Oliver Proc. IAHS, 374, 69-73, doi:10.5194/piahs-374-69-2016, 2016 Water research is one of South Australia's (SA's) highest priorities. Focus on water research became more critical during a drought that occurred between 1997 and 2011. Increased concern about water security for regional communities, industry and the environment led to the SA government establishing the Goyder Institute for Water Research to undertake cutting-edge science to inform the development of innovative integrated water management strategies to ensure SA's ongoing water security.

Description: East African wetland-catchment data base for sustainable wetland management Constanze Leemhuis, Esther Amler, Bernd Diekkrüger, Geofrey Gabiri, and Kristian Näschen Proc. IAHS, 374, 123-128, doi:10.5194/piahs-374-123-2016, 2016 Wetlands cover an area of approx. 18 Mio ha in the East African countries of Kenya, Rwanda, Uganda and Tanzania, with still a relative small share being used for food production. Current upland agricultural use intensification in these countries due to demographic growth, climate change and globalization effects are leading to an over-exploitation of the resource base, followed by an intensification of agricultural wetland use. We aim on translating, transferring and upscaling knowledge on experimental test-site wetland properties, small-scale hydrological processes, and water related ecosystem services under different types of management from local to national scale. This information gained at the experimental wetland/catchment scale will be embedded as reference data within an East African wetland-catchment data base including catchment physical properties and a regional wetland inventory serving as a base for policy advice and the development of sustainable wetland management strategies.

IAHS, 374, 85-91, doi:10.5194/piahs-374-85-2016, 2016 This paper is based on a project of Hydrometric Network Planning on Interprovincial Boundary River Sections through investigation and analysis of current hydrometric network, where, monitoring capability of the natural water cycle and water consumptions are analyzed, monitoring methodologies are summed up. Hydrological stations on interprovincial boundary waters are set up to meet the need of administrative water resources management.

Description: Conjunctive operation of river facilities for integrated water resources management in Korea Hwirin Kim, Cheolhee Jang, and Sung Kim Proc. IAHS, 374, 93-99, doi:10.5194/piahs-374-93-2016, 2016 This has been pursued to enable everyone to enjoy the benefits inherent to the utilization of water resources, by preserving functional rivers, improving their utility and reducing the degradation of water quality caused by floods and droughts. At the same time, coordinated activities are being conducted in multi-purpose dams, hydro-power dams, weirs, agricultural reservoirs and water use facilities with the purpose of monitoring the managemet of such facilities.

Description: Construction and evaluation of a Toolbox for the formulation of the Hydrologic component of the Basin Management Plans in Colombia Victor H. Garzón, Ricardo Garzón, Pedro M. Avellaneda, Erasmo A. Rodríguez, and Leonardo Alfonso Proc. IAHS, 374, 105-112, doi:10.5194/piahs-374-105-2016, 2016 HidroCHEP is a toolbox which supports the formulation and hydrologic characterization of Colombian basins. In this paper, we report the design, architecture, implementation and use of the toolbox, to understand the climatic variability of the country and to improve predictions in ungauged basins. It is demonstrated that the toolbox has the potential to support the formulation of basin management plans in the country and to contribute to integrated national water resources management.

Description: Hydrology and water resources in Caspian Sea Kourosh Haddadi Moghaddam Proc. IAHS, 374, 113-116, doi:10.5194/piahs-374-113-2016, 2016 Precipitation is the main driver of variability of the water balance over space and time, and changes in precipitation have very important implications for hydrology and water resources. Variations in precipitation over daily, seasonal, annual, and decadal timescales influence hydrological variability over time in a catchment. Flood frequency is affected by changes in the year-to-year variability in precipitation and by changes in short-term rainfall properties.

Description: Integrated management of water resources demand and supply in irrigated agriculture from plot to regional scale Niels Schütze and Michael Wagner Proc. IAHS, 373, 51-55, doi:10.5194/piahs-373-51-2016, 2016 Growing water scarcity in agriculture is an increasing problem and future climate predictions enhance drought risks for agricultural production. For assessing irrigation as a measure to increase agricultural water security a generalized stochastic approach for a spatial distributed estimation of future irrigation water demand is proposed, which ensures safe yields and a high water productivity at the same time.

Description: Quantification of resilience to water scarcity, a dynamic measure in time and space S. P. Simonovic and R. Arunkumar Proc. IAHS, 373, 13-17, doi:10.5194/piahs-373-13-2016, 2016 There are practical links between water resources management, climate change adaptation and sustainable development leading to reduction of water scarcity risk and re-enforcing resilience as a new development paradigm. Water scarcity, due to the global change (population growth, land use change and climate change), is of serious concern since it can cause loss of human lives and serious damage to the economy of a region. Unfortunately, in many regions of the world, water scarcity is, and will be unavoidable in the near future. As the scarcity is increasing, at the same time it erodes resilience, therefore global change has a magnifying effect on water scarcity risk. In the past, standard water resources management planning considered arrangements for prevention, mitigation, preparedness and recovery, as well as response. However, over the last ten years substantial progress has been made in establishing the role of resilience in sustainable development. Dynamic resilience is considered as a novel measure that provides for better understanding of temporal and spatial dynamics of water scarcity. In this context, a water scarcity is seen as a disturbance in a complex physical-socio-economic system. Resilience is commonly used as a measure to assess the ability of a system to respond and recover from a failure. However, the time independent static resilience without consideration of variability in space does not provide sufficient insight into system's ability to respond and recover from the failure state and was mostly used as a damage avoidance measure. This paper provides an original systems framework for quantification of resilience. The framework is based on the definition of resilience as the ability of physical and socio-economic systems to absorb disturbance while still being able to continue functioning. The disturbance depends on spatial and temporal perspectives and direct interaction between impacts of disturbance (social, health, economic, and other) and adaptive capacity of the system to absorb disturbance. Utility of the dynamic resilience is demonstrated through a single-purpose reservoir operation subject to different failure (water scarcity) scenarios. The reservoir operation is simulated using the system dynamics (SD) feedback-based object-oriented simulation approach.

Description: Predictions in ungauged basins – where do we stand? Günter Blöschl Proc. IAHS, 373, 57-60, doi:10.5194/piahs-373-57-2016, 2016 The spatial dimensions of water management heavily rely on accurate hydrological estimates in the landscape. This has been the focus of the Predictions in Ungauged Basins (PUB) initiative of the IAHS. The initiative has significantly advanced the science by furthering process understanding and estimation methods, and by synthesising the knowledge across processes, places and scales. Ongoing research on PUB is increasingly accounts for the feedbacks between humans and water in the landscape.

Description: A socio-hydrological comparative assessment explaining regional variances in suicide rate amongst farmers in Maharashtra, India Nadja I. den Besten, Saket Pande, and Hubert H. G. Savenije Proc. IAHS, 373, 115-118, doi:10.5194/piahs-373-115-2016, 2016 Maharashtra is one of the states in India that has witnessed highest rates of farmer suicides as proportion of total number of suicides. We interpret the crisis using a socio-hydrological model in two adjoining regions in Maharashtra, Marathwada and Desh, with higher farmer suicide rates in the former. The analysis confirms existing narratives: low (soil) water storage capacities, no irrigation and access to alternative sources of incomes are to blame for the crisis.

Description: Regionalization of post-processed ensemble runoff forecasts Jon Olav Skøien, Konrad Bogner, Peter Salamon, Paul Smith, and Florian Pappenberger Proc. IAHS, 373, 109-114, doi:10.5194/piahs-373-109-2016, 2016 For many years, meteorological models have been run with perturbated initial conditions or parameters to produce ensemble forecasts that are used as a proxy of the uncertainty of the forecasts. However, the ensembles are usually both biased (the mean is systematically too high or too low, compared with the observed weather), and has dispersion errors (the ensemble variance indicates a too low or too high confidence in the forecast, compared with the observed weather). The ensembles are therefore commonly post-processed to correct for these shortcomings. Here we look at one of these techniques, referred to as Ensemble Model Output Statistics (EMOS) (Gneiting et al., 2005). Originally, the post-processing parameters were identified as a fixed set of parameters for a region. The application of our work is the European Flood Awareness System ( http://www.efas.eu ), where a distributed model is run with meteorological ensembles as input. We are therefore dealing with a considerably larger data set than previous analyses. We also want to regionalize the parameters themselves for other locations than the calibration gauges. The post-processing parameters are therefore estimated for each calibration station, but with a spatial penalty for deviations from neighbouring stations, depending on the expected semivariance between the calibration catchment and these stations. The estimated post-processed parameters can then be used for regionalization of the postprocessing parameters also for uncalibrated locations using top-kriging in the rtop-package (Skøien et al., 2006, 2014). We will show results from cross-validation of the methodology and although our interest is mainly in identifying exceedance probabilities for certain return levels, we will also show how the rtop package can be used for creating a set of post-processed ensembles through simulations.

Description: Natural streamflow simulation for two largest river basins in Poland: a baseline for identification of flow alterations Mikołaj Piniewski Proc. IAHS, 373, 101-107, doi:10.5194/piahs-373-101-2016, 2016 Dams are major source of flow alteration and quantifying their impact is crucial from the point of view of the EU's environmental flow policy. This study demonstrates a method of assessing flow alteration by dams using a large-scale high-resolution hydrological model (SWAT) and three major Polish reservoirs as case studies. The results show that it has some advantages over more conventional methods, e.g. it allows for distinguishing between direct human effect and natural climatic effect.
