Fully revised and updated, this second edition of Water Ethics continues to consolidate water ethics as a key dimension of water-related decisions. The book introduces the idea that ethics are an intrinsic dimension of any water policy, program, or practice, and that understanding what ethics are being acted out in water policies is fundamental to an understanding of water resource management. Alongside updated references and the introduction of discussion questions and recommended further reading, this new edition discusses in depth three significant developments since the publication of the first edition in 2013. The first is the growing awareness of the climate crisis as an existential threat, and associated concern about adaptive strategies for sustainable water management and ways of using water management for climate mitigation (e.g., practically through agricultural soil management and conceptually through ethics awareness). Second, there has been increased clarity among the religious community, Indigenous leaders, and progressive academics that ethics needs to become an arena for application and action (e.g., the Vatican encyclical Laudato Si, protests at Standing Rock and Flint, Michigan, in the US, and climate demonstrations worldwide). Thirdly, there have been new normative water standards ranging from "water stewardship" (industry initiative), water charters (Berlin) and the on-going initiative to develop a global water ethics charter. Drawing on case studies from countries including Australia, India, the Philippines, South Africa, and the United States, this textbook is essential reading for students of environmental ethics and water governance and management.

Published in 1992, this book concentrates on recent developments, applications and aspects relating to numerical hydraulic models for predicting flow and water quality parameters in coastal, estuarine and river waters and river systems. The various chapters cover a range of different types of models and discuss the role of such numerical models for environmental impact assessment studies. The book is based on papers presented by leading experts in the field at a symposium held on 13 November 1991, organized by the Tyne and Humber Branch of the Institution of Water and Environmental Management. It covers the latest developments in modelling techniques and approaches and also the concepts of water quality modelling as required and seen from the viewpoints of regulatory agencies such as the NRA, consulting engineers and specialist modelling laboratories such as HR Wallingford and WRc. As well as an up-to-date review, it provides an understanding of the problems relating to water quality modelling, and the scope and requirements for using water quality models in the water industry. Readership includes practising engineers and scientists in the water industry, including consulting engineers, water companies and the NRA and other government departments, university and polytechnic libraries, staff and students and all other members of the water engineering profession.

Rural-Urban Water Struggles compiles diverse analyses of rural-urban water connections, discourses, identities and struggles evolving in the context of urbanization around the world. Departing from an understanding of urbanization as a process of constant making and remaking of multi-scalar territorial interactions that extend beyond traditional city boundaries and that deeply reconfigure rural-urban hydrosocial territories and interlinkages, the chapters demonstrate the need to reconsider and trouble the rural-urban dichotomy. The contributors scrutinize how existing approaches for securing urban water supply - ranging from water transfers to payments for ecosystem services - all rely on a myriad of techniques: they are produced by, and embedded in, specific institutional and legal arrangements, actor alliances, discourses, interests and technologies entwining local, regional and global scales. The different chapters show the need to better understand on-the-ground realities, taking account of inequalities in water access and control, as well as representation and cultural-political recognition among rural and urban subjects. Rural-Urban Water Struggles will be of great use to scholars of water governance and justice, environmental justice and political ecology. This book was originally published as a special issue of Water International.

Exclusive title covering effectiveness of DRASTIC model for groundwater vulnerability assessment Reviews of the strengths and limitations of assessment methods Presents multi-criteria evaluation of hydro-geological and anthropogenic factors Discusses integration with geographic information system (GIS) and remote sensing (RS) Includes application of groundwater governance framework with a case study study of a geographical setting

River systems around the world are degraded and are being used unsustainably. Meeting this challenge requires the development of flexible regimes that have the potential to meet essential consumptive needs while restoring environmental flows. This book focuses on how water trading frameworks can be repurposed for environmental water recovery and aims to conceptualise the most appropriate role for law in supporting recovery through these frameworks. The author presents a comprehensive study of the legal frameworks in four jurisdictions: the States of Oregon and Colorado in the western United States; the province of Alberta in Canada; and the Murray-Darling Basin in Australia/Basin State of New South Wales. A close comparative analysis of these four jurisdictions reveals a variety of distinctive regulatory arrangements and collaborations between public and private actors. In all cases, the law has been deployed to steer and coordinate these water governance activities. The book argues that each regime is based on a particular regulatory strategy, with different conceptions of the appropriate roles for, and relationships between, various actors and institutions. Legal frameworks do not have the capacity to rationalise and provide an overarching and absolute solution to the complex environmental and governance issues that arise in the context of environmental water transactions. Rather, the role of law in this context needs to be reconceptualised within the paradigm of regulatory capitalism as establishing and maintaining the limits within which regulatory participants can operate, innovate and collaborate.

This book is based on the discussions and papers prepared for the NATO Advanced Research Workshop that took place under the auspices of the NATO Security Through Science Programme and addressed urban water management problems. The workshop sought to critically assess the existing knowledge on Xenobiotics in urban water cycle, with respect to diverse conditions in participating countries, and promote close co-operation among scientists with different professional experience.

This book focuses on sustainable use and protection of transboundary aquifers located along the eastern border of European Union starting from the Baltic Sea and end in the Black Sea. The groundwater resources in this region play a very important role not only as a source of clean and safe drinking water, but also for social, economic and safety reasons. This publication sheds light on a wide range of real problems related to the management of groundwater, problems that are characteristic for most countries situated in the East European region. It also identifies potential threats that may materialise in the absence of cooperation between countries and appropriate measures to jointly manage the shared water resources in the region. Experience from some ongoing projects towards integrated management of transboundary aquifers (research, monitoring and data analysis) is reported. The book is addressed, in particular, to groundwater academics, researchers and experts as well as water management specialists interested in solving environmental issues extended to more than one country territory. On the other hand presented knowledge and experience would be also useful for decision makers especially to support environmental decision processes in border areas and work on preparation of international agreements on groundwater management.

With water as one of the most critical resources of nature that is necessary for sustaining life for all living things, it has become very important for designing and using spatial informational techniques for understanding the root causes behind the degradation of our water resources. This volume discusses in detail a selection of geospatial approaches, tools, and techniques. The uses of geographical information science to measure and manage water resources are diverse. Satellite remote sensing provides essential data for mapping water resources, hydrology flux measurement, monitoring drought, and flood inundation. With an abundance of informative case studies, the chapters discuss the use of the satellite remote sensing and GIS-based systems for managing urban storm water; for flood and soil erosion management; for mapping groundwater zones; for crop production, including measuring soil moisture and aridity; for gauging the impact of climate change; for evaluating glacier change dynamics; for assessing the impact of urban growth on water resources; for measuring the degradation of rivers; and more. This peer-reviewed volume imparts important information on spatial information techniques that are used for understanding the root causes behind the degradation of our water resources. GIScience for the Sustainable Management of Water Resources will be a valuable resource for urban planners, environmentalists, policymakers, ecologists, researchers, academicians, students, and professionals in the fields of remote sensing, civil engineering, social science, computer science, and information technology.

A review of the nation's new coverages serves as a ready reminder that drinking water safety is more than regional of local concern. In recent times, the print media alone has drawn attention to barium, bacteria, heavy metals, and increasingly organic contaminants, in public water supplies located in Florida, Rhode Island, Texas, Oregon, Illinois, Minnesota, North Carolina, Michigan, and California, to name a few. In an effort to address one of the major issues confronting the future of the nation's drinking water supplies, chemical contamination, the Drinking Water Research Foundation and the American Chemical Society presented the symposium, "Safe Drinking Water: the Impact of Chemicals on a Limited Resource." To add balance to the total presentation, two papers were included that were not part of the symposium.

This new book covers drinking water regulations such as disinfectant by-products, synthetic organics, inorganic chemicals, microbiological contaminants, volatile organic chemicals, radionuclides, fluoride, toxicological approaches to setting new national drinking water regulations, and trihalomethanes. In addition, organic and inorganic compounds scheduled to be regulated in 1989 and new candidates for the 1990s regulations are detailed.

Written by leading soil and ground-water remediation scientists, Handbook of Bioremediation presents information regarding the processes, application, and limitations of using remediation technologies to restore contaminated soil and ground water. It covers field-tested technologies, site characterization requirements for each remediation technology, and the costs associated with their implementation. In addition to discussions and examples of developed technologies, the book provides insights into technologies ranging from theoretical concepts to limited field-scale investigations. In situ remediation systems, air sparging and bioventing, the use of electron acceptors other than oxygen, natural bioremediation, and the introduction of organisms into the subsurface are among the specific topics covered in this invaluable handbook.

This volume focuses on practical aspects of sustainable water management in urban areas and presents a discussion of key concepts, methodologies, and case studies of innovative and evolving technologies. Topics include: (1) challenges in urban water resiliency; (2) water and energy nexus; (3) integrated urban water management; and (4) water reuse options (black water, gray water, rainwater). This volume serves as a useful reference for students and researchers involved in holistic approaches to water management, and as a valuable guide to experts in governmental agencies as well as planners and engineers concerned with sustainable water management systems in urban environments.

Approximately 80 per cent of the population of Latin America is concentrated in urban centres. Pressure on water resources and water management in cities therefore provide major challenges. Despite the importance of the issues, there has been little systematic coverage of the topic in book form. This work fills a gap in the literature by providing both thematic overviews and case study chapters. It reviews key aspects of why water matters in cities and presents case studies on topics such as groundwater management, green growth and water services, inequalities in water supply, the financing of water services and flood management. Detailed examples are described from Argentina, Brazil, Colombia, Ecuador, Mexico and Peru, and there is also a chapter comparing lessons which might be learnt from US cities. Contributing authors are drawn from both within and outside the region, including from the Inter-American Development Bank, OECD and World Bank to set the issues in a global context.

Water Crises and Governance critically examines the relationship between water crises and governance in the face of challenges to provide water for growing human demand and environmental needs. Water crises threaten the assumptions and accepted management practices of water users, managers and policymakers. In developed and developing world contexts from North America and Australasia, to Latin America, Africa and China, existing institutions and governance arrangements have unintentionally provoked water crises while shaping diverse, often innovative responses to management dilemmas. This volume brings together original field-based studies by social scientists investigating water crises and their implications for governance. Contributors to this collection find that water crises degrade environments, place untenable burdens on stakeholders, and produce or exacerbate social conflict, undermining ecological and social conditions that sustain effective collaboration. At the same time, water crises can promote institutional change that "resets" governance, promoting unusual and creative responses appropriate for local contexts. The studies in this volume provide evidence that, while water crises pose serious threats to environments and societies, they also provide opportunities to learn from experience and recraft water governance with coherent visions of more ecologically and socially sustainable futures. This volume was originally published as a special issue of Society & Natural Resources.

Water scarcity is not simply the result of what nature has to offer but always involves power relations and political decisions. This volume discusses the politics of the freshwater crisis, specifically how access to water is determined in different regions and historical periods, how conflict is constructed and managed, and how identity and efforts to control water systems, through development, technologies, and institutions, shape one another. The book analyzes responses to the water crisis as efforts to mitigate water insecurity and as expressions of collective identity that legitimate, resist, or seek to transform existing inequalities. The chapters focus on different processes that contribute to freshwater scarcity, including land use decisions, pollution, privatization, damming, climate change, discrimination, water management institutions and technology. Case studies are included from North and South America, Africa, Asia, Europe and New Zealand.

Reservoir operation is a multi-objective optimization problem, and is traditionally solved with dynamic programming (DP) and stochastic dynamic programming (SDP) algorithms. The thesis presents novel algorithms for optimal reservoir operation, named nested DP (nDP), nested SDP (nSDP), nested reinforcement learning (nRL) and their multi-objective (MO) variants, correspondingly MOnDP, MOnSDP and MOnRL. The idea is to include a nested optimization algorithm into each state transition, which reduces the initial problem dimension and alleviates the curse of dimensionality. These algorithms can solve multi-objective optimization problems, without significantly increasing the algorithm complexity or the computational expenses. It can additionally handle dense and irregular variable discretization. All algorithms are coded in Java and were tested on the case study of the Knezevo reservoir in the Republic of Macedonia. Nested optimization algorithms are embedded in a cloud application platform for water resources modeling and optimization. The platform is available 24/7, accessible from everywhere, scalable, distributed, interoperable, and it creates a real-time multiuser collaboration platform. This thesis contributes with new and more powerful algorithms for an optimal reservoir operation and cloud application platform. All source codes are available for public use and can be used by researchers and practitioners to further advance the mentioned areas.

Selenium (Se) and tellurium (Te) are metalloids of commercial interest due to their physicochemical properties. The water soluble oxyanions of these elements (selenite, selenate, tellurite and tellurate) exhibit high toxicities; hence, their release in the environment is of great concern. This study demonstrates the potential use of fungi as Se- and Te-reducing organisms. The response of Phanerochaete chrysosporium to the presence of selenite and tellurite was evaluated, as well as its potential application in wastewater treatment and production of nanoparticles. Growth stress and morphological changes were induced in P. chrysosoporium when exposed to selenite and tellurite. Synthesis of Se0 and Te0 nanoparticles entrapped in the fungal biomass was observed, as well as the formation of unique Se0-Te0 nanocomposites when the fungus was cultivated concurrently with Se and Te. The response of P. chrysosporium to selenite exposure was investigated in different modes of fungal growth (pellets and biofilm). A bioprocess for selenite removal and Se0 nanoparticles recovery using an up-flow fungal pelleted reactor was developed. 70% selenite removal (10 mg Se L-1 d-1) was achieved under continuous mode. The use of Se0 nanoparticles immobilized in P. chrysosporium pellets as a new sorbent material for the removal of heavy metals from wastewater was demonstrated.

This revised edition of the bestselling "Practice of Reservoir Engineering" has been written for those in the oil industry requiring a working knowledge of how the complex subject of hydrocarbon reservoir engineering can be applied in the field in a practical manner. Containing additions and corrections to the first edition, the book is a simple statement of how to do the job and is particularly suitable for reservoir/production engineers as well as those associated with hydrocarbon recovery.

This practical book approaches the basic limitations of reservoir engineering with the basic tenet of science: Occam's Razor, which applies to reservoir engineering to a greater extent than for most physical sciences - if there are two ways to account for a physical phenomenon, it is the simpler that is the more useful. Therefore, simplicity is the theme of this volume.
Reservoir and production engineers, geoscientists, petrophysicists, and those involved in the management of oil and gas fields will want this edition.

Water conflicts in India have now percolated to every level. They are aggravated by the relative paucity of frameworks, policies and mechanisms to govern the use of water resources. Based on the premise that understanding and documenting different types of water conflict cases in all their complexity would contribute to informed public debate and facilitate their resolution, Forum for Policy Dialogue on Water Conflicts in India, a collaborative initiative of the WWF project 'Dialogue on Water, Food and Environment', documented a number of such case studies. One of its kind in India, this book brings together an impressive sixty-three case studies - summarized status of the conflicts, the issues involved and their current position - and gives us a glimpse into 'the million revolts' that are brewing around water. While recognizing that each conflict is a microcosm of wider conflicts, the editors have classified these cases into eight broad themes that try to capture the dominant aspect of the conflict. These are: contending water uses; dams and displacement; equity-access-allocations; micro-level conflicts; water quality; trans-boundary conflicts; privatization; sand excavation and mining. With a mix of academics and activists as contributors, the book makes an important contribution to a new discourse on water in general, and water conflicts and conflict resolution in particular.

Dr. Hossen carried out an exceptional program of research in Bangladesh which focused on water governance in relation to human rights, international water law and environmental sustainability. His major argument is that eco-agricultural system encounters major disruptions due to a number of factors including regional hydropolitics and neoliberal and highly centralized approaches to water resource management that follow the principles of "ecocracy." In this context, Dr. Hossen explores three major questions: (i) How can local ecological knowledge be incorporated into national water policy? (ii) What strategies and reforms are required at the international watershed governance level? and (iii) How can human rights principles, including the principle of water as a human right, be used to formulate more effective water policy and governance principles? To answer these questions, Dr. Hossen explores the effects of regional hydropolitics on water management, focusing on three large engineering projects, the Farakka Barrage built by India on the Ganges River, and the Ganges-Kobodak (GK) and Gorai River Restoration (GRR) Projects in Bangladesh. This analysis is based on his research into local knowledge and farming practices during a year of fieldwork in 2011-12, focus group discussions, in-depth case studies and social survey methods. In addition to this primary data, he looks at extensive secondary documents from the government of Bangladesh pertaining to water management, agricultural modernization and institutional structures. The arguments herein are applicable particularly to the Ganges-Brahmaputra Basin countries in South Asia but also to the river basins of other parts of the world.

Seawater desalination is a rapidly growing coastal industry that is increasingly threatened by algal blooms. Depending on the severity of algal blooms, desalination systems may be forced to shut down because of clogging and/or poor feed water quality. To maintain stable operation and provide good feed water quality to seawater reverse osmosis (SWRO) systems, ultrafiltration (UF) pre-treatment is proposed. This research focused on assessing the ability of UF and other pre-treatment technologies to reduce biofouling in SWRO systems. An improved method to measure bacterial regrowth potential (BRP) was developed and applied at laboratory, pilot and full scale to assess the ability of conventional UF (150 kDa) and tight UF (10 kDa) alone and in combination with a phosphate adsorbent to reduce regrowth potential and delay the onset of biofouling in SWRO. The improved bacterial regrowth potential method employs a natural consortium of marine bacteria as inoculum and flow cytometry. The limit of detection of the BRP method was lowered to 43,000 +/- 12,000 cells/mL, which is equivalent to 9.3 +/- 2.6 g-Cglucose/L. The reduction in bacterial regrowth potential after tight UF (10 kDa) was 3 to 4 times higher than with conventional UF (150 kDa). It was further reduced after the application of a phosphate adsorbent, independent of pore size of the UF membrane. Pilot studies demonstrated that the application of tight UF (10 kDa) coupled with a phosphate adsorbent consistently lowered the bacterial regrowth potential and no feed channel pressure drop increase was observed in membrane fouling simulators (MFS) over a period of 21 days. The study also showed that non-backwashable fouling of UF membranes varied strongly with the type of algal species and the algal organic matter (AOM) they release. The presence of polysaccharide (stretching -OH) and sugar ester groups (stretching S=O) was the main cause of non-backwashable fouling. In conclusion, this study showed that an improved BRP method is suitable for the assessment of SWRO pre-treatment systems and it can be a useful tool to develop potential strategies to mitigate biofouling and improve the sustainability of SWRO systems.

Over the past two decades a quiet revolution has been taking place in the countryside of China where hundreds of millions of people have been lifted out of poverty. This book focuses on some of the practical actions and clever use of appropriate technologies which have been at the heart of this positive grassroots-driven change in rural Gansu Province. Key to this has been mobilizing the population and their expeditious use of rainwater harvesting both to dramatically improve crop yields and provide households with reliable domestic water supplies. Since Gansu is semi-arid and stored rainwater a scarce resource, ingenious systems of providing crops with just the right amount of supplementary irrigation at critical periods have been developed. Challenges such as lack of fuelwood have been overcome by the development of simple low-cost solar cookers, which by focusing the sun s rays using tiny mirrors can boil a kettle in minutes. These affordable units are now being produced at hundreds of small rural factories. The construction of low-cost greenhouses using plastic sheeting allows for the collection of rainwater and its use in efficient drip irrigation systems. By supplying vegetables and cash crops to local markets farmers have been able to repay their initial investment in under two years. The real significance of this case study is that most of the approaches described are based on universal principles of sustainable development. "Every Last Drop" is recommended reading for engineers, planners, staff of NGOs, academics and students in the water, energy, and agriculture sectors."
