    Description: The sustainability of water resources worldwide is increasingly imperiled as climate change contributes to the human-induced problems of water supply scarcity and maldistribution. Environmental problems associated with water quality, such as aquifer depletion, land subsidence, the seasonal drying of river flows, waterlogging, the salinization of rivers and groundwater, and human health problems from the excessive use of fertilizers and pesticides will require a radical re-thinking of resource-management policy and new tools to help analysts and regulators craft novel solutions. Over the past several decades, with the advent and rapid progress of computational technology, watershed models have increasingly become important and effective tools for tackling a wide range of water resource and environmental management issues and for supporting regulatory compliance. Statistical and machine-learning methods are being used to support and even supplant more traditional simulation models to improve the estimation of the temporal dynamics and patterns of variability in pollutant concentrations and loads. With the advancements in modeling approaches for water quality, there have also been developments in decision-support tools for water quality management. This reprint describes innovative decision-support approaches from around the world and across sectors that can be applied by stakeholders, government entities, and regulators to reduce environmental pollution and result in cost-effective and sustainable water management strategies.

    Description: In recent decades, the environmental impact of organic pollutants, especially persistent and emerging organic pollutants, has attracted widespread attention, and related research has been rapidly developed. Organic pollutants represent a popular topic of research in the environmental field. Large amounts of organic pollutants, which are widely distributed in air, water, sediment, soil, and other environmental media, are created via industrial production and other human activities. A series of research projects have been carried out regarding the development of analytical methods for organic pollutants, the distribution of environmental media, environmental concentration, environmental fate, the exploration of new pollutants, and the non-target analysis of organic pollutants.

    Description: In the last few centuries, the study of sea-level changes along the world's shores has been a primary scientific focus in analyses of climate change, but also for scientists exploring past landscape evolution, geomorphological processes, human impacts, and system responses. The relative variation in sea level derives as a result of global, regional, and local processes. All these processes are spatially and temporally variable and cause complex sea-level changes at both regional and local scales. A multidisciplinary approach addressed to palaeo sea-level reconstructions at regional and local scale is the best method to understand the role of natural and anthropogenic forcing in the landscape evolution, as well as to discover the historical human adaptions to natural modifications of the landscape. Definitely, investigating these regional and local patterns is mandatory to reconstruct possible scenarios of the relative sea level rise impacts and to prepare the adaptation of coastal communities threatened by future climate changes. The aim of this Special Issue has been to collect contributions addressing and discussing methodological and multi-disciplinary approaches to studying the regional and local coastal modifications in relation to historical and recent relative sea-level changes to hypothesize future trends.

    Description: At present, cyanobacteria and their toxins (also known as cyanotoxins) constitute a major threat for freshwater resources worldwide. Cyanotoxin occurrence in water bodies around the globe is constantly increasing, whereas emerging, less studied or completely new variants and congeners of various chemical classes of cyanotoxins, as well as their degradation/transformation products are often detected. In addition to planctic cyanobacteria, benthic cyanobacteria, in many cases, appear to be important toxin producers, although far less studied and more difficult to manage and control. This Special Issue highlights novel research results on the structural diversity of cyanotoxins from planktic and benthic cyanobacteria, as well as on their expanding global geographical spread in freshwaters.

    Description: This reprint describes the fate of pollutants transported to the sea from the mainland and how they accumulate in the marine environment and organisms. This will contribute to increasing the knowledge on the dangers of pollutants that reach the marine environment and their fate once they enter the marine food chain. We also hope to improve knowledge on the effects of the pollutant load on the sea during all the seasons, due to the contribution of rivers, rainfall, etc., and the relative influence on marine organisms.

    Description: Climate and anthropogenic changes impact the conditions of erosion and sediment transport in rivers. Rainfall variability and, in many places, the increase of rainfall intensity have a direct impact on rainfall erosivity. Increasing changes in demography have led to the acceleration of land cover changes in natural areas, as well as in cultivated areas, and, sometimes, in degraded areas and desertified landscapes. These anthropogenized landscapes are more sensitive to erosion. On the other hand, the increase in the number of dams in watersheds traps a great portion of sediment fluxes, which do not reach the sea in the same amount, nor at the same quality, with consequences on coastal geomorphodynamics. This book is dedicated to studies on sediment fluxes from continental areas to coastal areas, as well as observation, modeling, and impact analysis at different scales from watershed slopes to the outputs of large river basins. This book is concentrated on a number of keywords: “erosion” and “sediment transport”, “model” and “practice”, and “change”. The keywords are briefly discussed with respect to the relevant literature. The contributions in this book address observations and models based on laboratory and field data, allowing researchers to make use of such resources in practice under changing conditions.

    Description: Freshwater macroinvertebrates play a crucial role in linking sediments and their processes to the food web. Indeed, environmental modifications (e.g., nitrogen deposition, salinity, and temperature increase), pollution (e.g., pesticides and heavy metals), and introduction of alien species are the main drivers of changes that are affecting their communities. This Special Issue aims to present the past and present knowledge on freshwater macroinvertebrates to understand their role as providers of ecosystem services, to highlight the effects of global changes on their community (in the short and long term), and to underline major gaps in their study. Finally, in order to tackle the currently unsustainable use of freshwater natural capital, we welcome ideas and expert opinions on the development of future research linked to national and international regulations.

    Description: This Special Issue aims to provide new insights into the issue of the mercury contamination of terrestrial and aquatic ecosystems. This ubiquitous contaminant has been used by humans for many years, resulting in global contamination. When this toxic contaminant is converted to methylmercury, it accumulates in trophic chains, which is a major issue for wildlife and human health. The nine articles contained within this Special Issue on ‘‘Mercury and Methylmercury Contamination of Terrestrial and Aquatic Ecosystems’’ endeavour to identify the historical evolution of Hg and MeHg levels in aquatic environments, and to evaluate the impact of current and historical human activities, such as mining, climate change, and soil erosion, on receptor ecosystems and food chains.

    Description: The development of civilization entails a growing demand for consumer goods. A side effect of the production and use of these materials is the production of solid waste and wastewater. Municipal and industrial wastewater usually contains a large amount of various organic compounds and is the main source of pollution of the aquatic environment. Therefore, the search for effective methods of wastewater and other polluted water treatment is an important element of caring for the natural environment. This book presents research on the determination and removal of environmentally hazardous organic compounds from aqueous samples. The articles included in this book describe the results of examinations, at the laboratory scale, of the efficiency of chemical as well as physical processes for the removal or degradation of selected model pollutants. Environmental studies, especially those concerning the determination of trace impurities, require effective isolation and concentration procedures. The methods used for this purpose should meet the requirements of green chemistry. The liquid phase microextraction procedures and use of electrochemical methods described in this book seem to be proper for environmental studies, as they are effective and environmentally friendly.

    Description: The interface of 440,000 km long coastline in the world is subject to global change, with an increasing human pressure (land use, buildings, sand mining, dredging) and increasing population. Improving our knowledge on involved mechanisms and sediment transport processes, monitoring the evolution of sedimentary stocks and anticipating changes in littoral and coastal zones is essential for this purpose. The special issue of Water on “Sediment transport in coastal waters” gathers thirteen papers which introduce the current revolution in the scientific research related to coastal and littoral hydrosedimentary dynamics, and reflect the diversity of concerns on which research in coastal sediment transport is based, and current trends — topics and preferred methods — to address them.

    Description: Carbon dioxide (CO2) emissions, resulting from the combustion of fossil fuels by human activity, reinforce the greenhouse effect and cause climate disruption. While public awareness of this global problem is growing, ocean acidification, described as "the other CO2 problem", is still largely unknown. This book answers ten key questions on the biogeochemical foundations of acidification, past, current and future trends, the impact on marine organisms and on humans, and finally, ways to remedy the situation. It draws its answers from fields as diverse as biogeochemistry, ecology, physiology, evolution, aquaculture and fisheries, economics and sociology.

    Description: Many of the world's large lakes are, in fact, not large enough to cope with the uses to which they are put by human activities, as they have been going on for over a century. The limits of these continental-scale macro-ecosystems are reflected in a whole series of pathologies that affect them and are accompanied by a deterioration in the ecosystem services provided: fishing, water supply, self-purification, dilution of pollution, cultural and recreational services, etc. In addition, all of the tensions involved are now exercised in a context of multi-stress due to climate change. The "large lake" size, inertia and complexity with which it endows the systems concerned, results in new conditions of exposure and responses, difficult to integrate in terms of management. The book offers a multidisciplinary analysis of various restoration experiments carried out on large lakes around the world (successes and failures). Rich in lessons on the safeguarding and preservation of the world's lake heritage, this study opens up avenues of reflection on the future ecological challenges to be met in order to prepare the "lake-watershed-society" systems for the new situation, in terms of climate and pollution. This book is intended for students, teachers and researchers, lake managers, as well as the general public interested in the preservation and restoration of large lakes.

    Description: Deep biosphere research is at the scientific frontier of bio- and geo-related sciences, yet it is largely underexplored. In terms of volume, deep subsurface settings represent some of the largest microbial habitats on the planet, and the combined biomass of the deep biosphere encompasses the largest living reservoir of carbon, excluding land plants. However, the paleo-record of the deep biosphere is still largely uncharted and neglected. The aim of this book is to highlight current research on deep life through time and bring together researchers with various perspectives. The book presents a collection of scientific contributions that provide a sample of forefront research in this field. The contributions involve a range of case studies of deep ancient life in continental and oceanic settings, of microbial diversity in sub-seafloor environments, and of the isolation of calcifying bacteria, as well as reviews on clay mineralization of fungal biofilms and on the carbon isotope records of the deep biosphere. Deciphering the fossil record of the deep biosphere is a challenging task but, when successful, will unlock doors to life’s cryptic past.

    Description: Different types of pressures, such as nutrients, micropollutants, microbes, nanoparticles, microplastics, or antibiotic-resistant genes, endanger the quality of water bodies. Evidence-based pollution control needs to be built on the three basic elements of water governance: Monitoring, modeling, and management. Monitoring sets the empirical basis by providing space- and time-dependent information on substance concentrations and loads, as well as driving boundary conditions for assessing water quality trends, water quality statuses, and providing necessary information for the calibration and validation of models. Modeling needs proper system understanding and helps to derive information for times and locations where no monitoring is done or possible. Possible applications are risk assessments for exceedance of quality standards, assessment of regionalized relevance of sources and pathways of pollution, effectiveness of measures, bundles of measures or policies, and assessment of future developments as scenarios or forecasts. Management relies on this information and translates it in a socioeconomic context into specific plans for implementation. Evaluation of success of management plans again includes well-defined monitoring strategies. This book provides an important overview in this context.

    Description: The papers in this SI present valuable results in the topics of soils, sediments, and water contamination according to the consideration of ecological and health risk. They also point out open questions and possible avenues for future research. Biochar application can benefit both soil conservation and contamination, but further research should be conducted to investigate whether these positive effects can be extended to the field scale. Similar to biochar, scale-up design will be helpful for thin-layer capping in in situ sediments using mixed active amendments. Both physiochemical analysis and bioassays mutually supported the evaluation results of river water quality. However, we need better approaches and policies for management to prevent further contamination from the discharge of untreated industrial and domestic waste into this aquatic ecosystem. The use of microorganisms to eliminate antibiotics is a promising strategy, but future work should verify the biodegradation ability of antibiotic-degrading bacteria in wastewater treatment plants.

    Description: This Special Issue titled “Soil Erosion and Sustainable Land Management” presents 13 chapters organized into four main parts. The first part deals with assessment of soil erosion that covers historical sediment dating to understand past environmental impacts due to tillage; laboratory simulation to clarify the effect of soil surface microtopography; integrated field observation and the random forest machine learning algorithm to assess watershed-scale soil erosion assessment; and developing the sediment delivery distributed (SEDD) model for sub-watershed erosion risk prioritization. In Part II, the factors controlling soil erosion and vegetation degradation as influenced by topographic positions and climatic regions; long-term land use change; and improper implementation of land management measures are well dealt with. Part III presents different land management technologies that could reduce soil erosion at various spatial scales; improve land productivity of marginal lands with soil microbes; and reclaim degraded farmland using dredged reservoir sediments. The final part relates livelihood diversification to climate vulnerability as well as the coping strategy to the adverse impacts of soil erosion through sustainable land management implementation which opens prospects for policy formulation. The studies cover regions of Africa, Europe, North America and Asia, being dominantly conducted under the framework of international scientific collaborations through employing a range techniques and scales, from the laboratory to watershed scales. We believe those unique features of the book could attract the interest of the wider scientific community worldwide.

    Description: The term “algae” refers to a large diversity of unrelated phylogenetic entities, ranging from picoplanktonic cells to macroalgal kelps. Marine algae are an important primary producer in the marine food chain, responsible for the high primary production of coastal areas, providing food resources in situ for many grazing species of gastropods, peracarid crustaceans, sea urchins or fish. Recent findings indicate that marine environments have rapidly changed due to global warming over the past several decades. This change has led to significant variations in marine algal ecology. For example, a long-term increase in ocean temperatures due to global warming has facilitated the intensification of harmful algal blooms, which adversely impact public health, aquatic organisms, and aquaculture industries. Thus, extensive studies have been conducted, but there is still a gap in our understanding of the variation in their ecology in accordance with future marine environmental changes. To fill this gap, studies on the taxonomy and ecology of marine algae are highly necessary. We have invited algologists to submit research articles that enable us to advance our understanding of the taxonomy and ecology of marine algae. Fourteen papers have been collected so far, which cover different aspects of the taxonomy and ecology of marine algae, including understudied species, interspecific comparisons, and new techniques.

    Description: The state-of-the-art in water-worked bed hydraulics can only be examined through a careful exploration of the experimental (both laboratory and field) results via theoretical development. This book is primarily focused on the research aspects that involve a comprehensive knowledge of sediment dynamics in turbulent flows, as the most up-to-date research findings in the field are presented. It begins with two reviews on bedload transport and water-work bed experimental studies. The sediment dynamics is then analyzed from a classical perspective by applying the mean bed shear approach and additionally incorporating a statistical description for the role of turbulence. The work finally examines the local scour problems at hydraulic structures and results from field studies. It is intended as a course guide for field professionals, keeping up with modern technological developments. Therefore, as a simple prerequisite, readers should have a basic knowledge of hydraulics to an undergraduate level.

    Description: The anthropogenic loading of phosphorus (P) to water bodies continues to increase worldwide, in many cases leading to increased eutrophication and harmful algal blooms. Determining the sources of P and the biogeochemical processes responsible for this increase is often difficult because of the complexity of the inputs and pathways, which vary both in spatial and temporal scales. In order to effectively develop strategies to improve water quality, it is essential to develop a comprehensive understanding of the relationship of P pools with biological uptake and cycling under varied soil and water conditions. In this ebook, eight chapters cover the various aspects of basic-applied research on mineral–P interaction and how these reactions impact P mobilization, bioavailability, transfer, and speciation of P in different soil matrices using advanced analytical methods. Some of these methods include the application of XANES and field-based research related to stream bank legacy nutrients; natural and anthropogenic eutrophication and its relationship to climate change; and the evaluation of the impact of P due to (i) grazing systems, (ii) weathering and vegetation, and iii) soil and manure management practices. In addition, two review chapters take a holistic approach to cover an expansive area of P transformation processes along the cropland–riparian–stream continuum and the assessment of legacy P. Together, these contributions improve our current understanding of the reactions and processes that impact P concentration, speciation, cycling, loss, and transfer from agroecosystems.

    Description: The recognition of global climate change as an environmental issue has drawn attention to the climatic impact of human activities. Scientists and environmentalists have pointed out that human-induced climate change results from disturbances in all aspects of the environment. Among them, aquatic environments (including water, sediments, aquatic organisms, etc.,) are closely related to all kinds of human interference. However, they are under increasing stress due to climate change and human disturbances, such as an increased input of pollutants, a loss of biodiversity and a decrease in ecological functions. Fortunately, realizing the urgency and importance of the matter, researchers have started to work on coping strategies, including effective water treatment and energy recovery. This Special Issue focuses on revealing the effects of climate change and anthropogenic disturbances on water ecological environments, analyzing physical, chemical and biological aspects.

    Description: Biocultural restoration is a process by which the various connections between humanity and nature, as well as between People and Place are revived to restore the health and function of social-ecological systems. This collection explores the subject of biocultural restoration and does so within the context of Hawaiʻi, the most remote archipelago on the planet. The Hawaiian Renaissance, which started in the 1970s, has led to a revival of Hawaiian language, practices, philosophy, spirituality, knowledge systems, and systems of resource management. Many of the leading Indigenous and local scholars of Hawaiʻi who were born into the time of the Hawaiian Renaissance contributed to this collection. More than a third of the authors are of Indigenous Hawaiian ancestry; each paper had at least one Indigenous Hawaiian author, and several papers had a Hawaiian lead author, making this the largest collection to date of scientific publications authored by Indigenous Hawaiians (Kānaka ʻŌiwi). In addition, the majority of authors are women, and two of the papers had 100 percent authorship by women. This collection represents a new emphasis in applied participatory research that involves academics, government agencies, communities and both private and non-profit sectors.

    Description: This book is meant as an introduction to the field of colloid science, i.e. the study of the behaviour of micrometric particles in a fluid (or a gas). The book was written with a special emphasis on sediment particles. Sediment particles are complex colloidal particles due to their composition, shape and interaction with their environment. Characterization of the colloidal fraction of sediment is done by recording, among others, the particles’ size, shape and electric surface charge and evaluating their density or their interactions. These properties are important for civil engineering applications. Large-scale sediment transport models for example require as input the settling velocity of particles. In concentrated areas, this velocity becomes a function of the particles’ concentration and particle-particle interactions lead to the creation of larger particles, called flocs. These flocs can settle and, when reaching the bed, consolidate in time. All these aspects, and related models, are treated in the present book.

    Description: In the research on environmental hydraulics, its turbulence, and its sediment transport, constant challenges have been faced. The complexity of hydraulic impacts on sediment transport and turbulent flow properties makes research in this area a difficult task. However, due to pressure from climate change and the mounting issue of pollution, environmental flow studies are more crucial than ever. Bedforming within rivers is a complex process that can be influenced by the hydraulics, vegetated field, and various suspended and bedload transports. Changes in flow conditions due to rain and flood can further complicate a hydraulic system. To date, the turbulence, morphologic, and bedforming characteristics of natural environmental flows are still not well understood. This book aims to bring together a collection of state-of-the-art research and technologies to form a useful guide for the related research and engineering communities. It may be useful for authorities, researchers, and environmental, civil, and water engineers to understand the current state-of-the-art practices in environmental flow modelling, measurement, and management. It may also be a good resource for research, post-, or undergraduate students who wish to know about the most up-to-date knowledge in this field.

    Description: Author(s): Rémi Blandino, Marco Barbieri, Philippe Grangier, and Rosa Tualle-Brouri The employ of a heralded noiseless linear amplifier has been proven as a useful tool for mitigating imperfections in quantum channels. Its analysis is usually conducted within specific frameworks, for which the set of input states for a given protocol is fixed. Here we obtain a more general descript... [Phys. Rev.

    Description: Author(s): Xiangming Hu For dark resonance, one of the most remarkable coherent effects in light-matter interactions, it has commonly been expected that squeezing and entanglement, if existent, are formed via coherent evolutions against dissipation. Contrary to the expectations, here we show that dissipation generates enta… [Phys. Rev. A 92, 022329] Published Wed Aug 12, 2015
