    Abstract: This book carefully considers hydrological models which are essential for predicting floods, droughts, soil moisture estimation, land use change detection, geomorphology and water structures. The book highlights recent advances in the area of hydrological modelling in the Ganga Basin and other internationally important river basins. The impact of climate change on water resources is a global concern. Water resources in many countries are already stressed, and climate change along with burgeoning population, rising standard of living and increasing demand are adding to the stress. Furthermore, river basins are becoming less resilient to climatic vagaries. Fundamental to addressing these issues is hydrological modelling which is covered in this book. Integrated water resources management is vital to ensure water and food security. Integral to the management is groundwater and solute transport, and this book encompasses tools that will be useful to mitigate the adverse consequences of natural disasters.

    Details
    Keywords: Geographic information systems. ; Natural disasters. ; Landscape ecology. ; Physical geography. ; Geographical Information System. ; Natural Hazards. ; Landscape Ecology. ; Physical Geography.
    Description / Table of Contents: Introduction -- Preface -- Section-I : Land Use Land Cover Dynamics -- Section-II: Agriculture water Management.-Section III: Water Resources Assessment and Modelling -- Section IV: Natural Disasters -- Conclusions and Recommendations.
    Abstract: This book focuses on the application of geospatial technologies to study the land use land cover (LULC) dynamics, agricultural water management, water resources assessment and modeling, and studies on natural disasters. LULC dynamics is one of the major research themes for studying global environmental change using remote sensing data. The section on LULC dynamics covers the multi-variate criteria for land use and land cover classification and change assessment in the mountainous regions. Further, LULC change detection of the Tons river basin and LULC dynamics at decadal frequency are studied to derive adaptation and mitigation strategies. Landscape-level forest disturbance modeling, together with conservation implications, is also included. The watershed management approach is necessary for comprehensive management of land and water resources of any region, where studies on multi-criteria analysis for rainwater harvesting planning and its impact on land use land cover transformations in rain-fed areas using geospatial technologies are presented in this book. The book will be useful for academics, water practitioners, scientists, water managers, environmentalists, and administrators, NGOs, researchers, and students who are actively involved in the application of geospatial technologies in LULC studies, agricultural water management and hydrological modelling and natural disasters for addressing the challenges being posed by climate change while addressing issues of food and water securities .

    ICON‐O: The Ocean Component of the ICON Earth System Model—Global Simulation Characteristics and Local Telescoping Capability (2022)
    Details
    Publication Date: 2023-01-25
    Description: We describe the ocean general circulation model Icosahedral Nonhydrostatic Weather and Climate Model (ICON‐O) of the Max Planck Institute for Meteorology, which forms the ocean‐sea ice component of the Earth system model ICON‐ESM. ICON‐O relies on innovative structure‐preserving finite volume numerics. We demonstrate the fundamental ability of ICON‐O to simulate key features of global ocean dynamics at both uniform and non‐uniform resolution. Two experiments are analyzed and compared with observations, one with a nearly uniform and eddy‐rich resolution of ∼10 km and another with a telescoping configuration whose resolution varies smoothly from globally ∼80 to ∼10 km in a focal region in the North Atlantic. Our results show first, that ICON‐O on the nearly uniform grid simulates an ocean circulation that compares well with observations and second, that ICON‐O in its telescope configuration is capable of reproducing the dynamics in the focal region over decadal time scales at a fraction of the computational cost of the uniform‐grid simulation. The telescopic technique offers an alternative to the established regionalization approaches. It can be used either to resolve local circulation more accurately or to represent local scales that cannot be simulated globally while remaining within a global modeling framework.
    Description: Plain Language Summary: Icosahedral Nonhydrostatic Weather and Climate Model (ICON‐O) is a global ocean general circulation model that works on unstructured grids. It rests on novel numerical techniques that belong to the class of structure‐preserving finite Volume methods. Unstructured grids allow on the one hand a uniform coverage of the sphere without resolution clustering, and on the other hand they provide the freedom to intentionally cluster grid points in some region of interest. In this work we run ICON‐O on an uniform grid of approximately 10 km resolution and on a grid with four times less degrees of freedom that is stretched such that in the resulting telescoping grid within the North Atlantic the two resolutions are similar, while outside the focal area the grid approaches smoothly ∼80 km resolution. By comparison with observations and reanalysis data we show first, that the simulation on the uniform 10 km grid provides a decent mesoscale eddy rich simulation and second, that the telescoping grid is able to reproduce the mesoscale rich circulation locally in the North Atlantic and on decadal time scales. This telescoping technique of unstructured grids opens new research directions.
    Description: Key Points: We describe Icosahedral Nonhydrostatic Weather and Climate Model (ICON‐O) the ocean component of ICON‐ESM 1.0, based on the ICON modeling framework. ICON‐O is analyzed in a globally mesoscale‐rich simulation and in a telescoping configuration. In telescoping configuration ICON‐O reproduces locally the eddy dynamics with less computational costs than the uniform configuration.

    Distinctive Response of Magnetosphere-Ionosphere-Thermosphere system to the Geomagnetic Storms of different solar origin: Inference from the TIMED-SABER satellite observations (2023)
    In:  XXVIII General Assembly of the International Union of Geodesy and Geophysics (IUGG)
    Details
    Publication Date: 2023-08-30
    Description: The solar energy deposited into Earth’s magnetosphere-ionosphere-thermosphere (MIT) system, during the geomagnetic storms, significantly perturbs the thermospheric structure, chemistry and energetics. This energy is dissipated due to the Joule heating and thermospheric cooling mechanisms by Nitric Oxide (NO) via 5.3 µm and Carbon Dioxide (CO2) via 15 µm. The latter processes effectively regulate the thermospheric temperature and are well known as natural thermostat. We utilize the NO at 5.3 µm and CO〈sub〉2〈/sub〉 at 15 µm radiative emissions as observed by the SABER (Sounding of the Atmosphere using Broadband Emission Radiometry) instrument onboard the NASA’s TIMED (Thermosphere Ionosphere Mesosphere Energetics Dynamics) satellite to investigate the response of the magnetosphere-ionosphere-thermosphere system to the geomagnetic storms of different solar origin. It is observed that both the magnitude and temporal variations of the radiative cooling processes strongly depend on the solar origin of the geomagnetic storm. We exploit the particle flux as measured by the DMSP (Defense Meteorological Satellite Program) satellite, the GRACE (Gravity Recovery and Climate Experiment) satellite observations of atmospheric density, and solar wind-magnetosphere coupling functions from the SuperMAG database to explore the possible mechanisms responsible for the distinctive behaviour.

    ORBYTS project: Predicting storm times with machine learning (2023)
    In:  XXVIII General Assembly of the International Union of Geodesy and Geophysics (IUGG)
    Details
    Publication Date: 2023-08-29
    Description: Historically there has been a lack of diversity in STEM subjects, including physics. Often to counteract this many outreach programs try and encourage young people, especially young girls, to pick up sciences. However, often these outreach programs are one-time events. ORBYTS (Original Research By Young Twinkle Students) goes about this differently. Scientists are paired with local schools to work on a novel, scientific-relevant project over 3 months with weekly 1-1.5h sessions. This way students are introduced to what and how research works by conducting research themselves, thus hopefully solidifying their interest in STEM. To assess this, we ask them at the end of the project to fill out a questionary on how participating in this project impacted their likelihood to keep sciences in upper secondary school and to pursue a STEM-related career. For this project, the students use machine learning to predict storm times, which is a problem that space weather scientists are trying to solve. Machine learning has proven to be successful in other fields and its use is becoming more frequent in the space weather community. The students build a random forest on individual stations in the CARISMA magnetometer chain with magnetic field data and solar wind parameters to assess whether there is a geomagnetic storm or not. Each random forest is trained with the storm time list provided by Sandhu et al. 2021 and its performance is evaluated on a selection of unseen data. The different models are then compared to determine the impact of location on the prediction.

    Curating Robert E. Horton's Collective Works (2023)
    In:  XXVIII General Assembly of the International Union of Geodesy and Geophysics (IUGG)
    Details
    Publication Date: 2023-06-29
    Description: Robert E. Horton (1875-1945) had a prolific career in hydrology with an estimated contribution of ~200 works (papers, reports and commentaries). In the last few decades, independent works by scientists led to curation of bibliographies that include ~80-135 of his works. In our recent work (2022), we consolidated and extended the available bibliographies to create a more comprehensive one of 168 works. These works span a wide range of subjects, which can be classified into applied physics (process understanding of evaporation, runoff, precipitation, groundwater), applied mathematics (probability, calculus), engineering (hydraulic design, flow regulation, reservoir operation), and management (economics, policy, and social science). Our goal is to: 1) summarize the 168 works and extend the bibliography; 2) comb through the 168 works to identify subject themes, their volume and density; 3) link them to the 94 archive boxes held in the U.S. National Archive in Maryland where Horton’s unpublished works are held; 4) quantify untapped scientific potential in various subjects, especially by identifying his major monographs and unfinished works; 5) trace his scientific inspirations to scientists of the preceding centuries, especially those scientists whose voluminous works Horton evidently studied in-depth, e.g. Paolo Frisi from Italy (1700s) for Hydro-geomorphology; and John Dalton (1800s) and Geoffrey. I. Taylor (1900s) for Evaporation. We surmise that much of Horton’s work is still to be discovered for its inspirational and entertaining value, as well as the remarkable predictive accuracy of his theories, which calls for renewed attention to his diverse contributions.
