The authors of this in-depth study describe the theory and techniques that can be applied to the specific case of valuing potable water provided by groundwater supplies. The theory and techniques can be extended to valuing drinking water provided by surface water supplies, and also to valuing alternative levels of water quality. The theory and case studies discussed in the book suggest that important determinants of the economic value of water quality include: the probability of contamination measured objectively and subjectively, information on actual levels of contamination in household water supplies, socioeconomic characteristics of households, and the extent to which the values of water quality people hold include non-use components. The case study results also suggest that empirical valuation results are sensitive to study design effects such as the particular statistical technique used to estimate mean or median values. These results suggest that estimating water quality values using benefits transfer techniques is problematic, but perhaps feasible with improved data and valuation models. Government agencies, private consulting firms and NGOs involved in water quality policy as well as academic researchers, professors and students will find this volume of theory, application and technique an invaluable reference.
In the contemporary West, pressures to more effectively reallocate
water to meet growing urban and environmental demands are
increasing as environmental awareness grows and climate change
threatens existing water supplies.
This book embodies the potentials of nanobiotechnology-based water treatment techniques to provide a solid understanding of the subjects. Starting with a refresher of the basic conventional technologies which are now been integrated with nanomaterials for an efficient, viable, and eco-friendly treatment of contaminated water. The book covers various physical, chemical, and hybrid methods of nanobiomaterial synthesis and their fabrication for characterizing existing techniques. The book gives special attention to those nanotechnology-based approaches that promise easier, faster, and cheaper processes in contaminants monitoring and their treatment. Several case studies explain in an easy to understand format how employing nanobiomaterials as an indicator and analytical tool will enable students to learn about cleaning up the environment.

Under this theme, the congress covers a broad range of topics and provides an excellent opportunity for academics, engineers, scientists, government officials, regulators, and planners to present, discuss and exchange notes on the latest advances and developments in the research and application of environmental geotechnics.
Attending water security is an important challenge and a major systemic risk humanity faces in the years to come. This is due to population increase, over-consumption of water, especially in agriculture, climate change and various forms of water pollution. The issue becomes more complicated in transboundary water catchments that cover almost half of the world's land surface, with about 60% of global river flow and 40% of the world's population. Also, in many parts of the planet, like Saharan Africa, population depends on groundwater resources located in transboundary aquifer systems. These facts illustrate the importance of the book's subject, which is the governance of transboundary waters, both surface and groundwater. The book is written by two distinguished scientists, who, having worked in various international institutions, like UNESCO, GEF, UNEP and at the European Commission, have both an extended expertise on how to bridge the gap between science and political decision-making, which is the main factor for an effective governance of water resources. What is new in the book is the integrated analysis of transboundary governance of both surface water and groundwater, as it occurs in reality. In current literature, groundwater is still often missing for the benefit of surface water or, on the contrary, it is treated separately from surface water. The most important feature of the book is to distinguish between the real and a "good" or an effective transboundary water governance and to provide practical tools, methodologies and examples for its implementation in the field. Published timely during 2018, the book will contribute to address successfully practical problems of governance of transboundary waters that represent a very important part of our precious fresh water resources.
Urban Water Distribution Networks: Assessing Systems Vulnerabilities and Risks provides a methodology for a system-wide assessment of water distribution networks (WDN) based on component analysis, network topology and, most importantly, the effects of a network's past performance on its seismic and/or non-seismic reliability. Water distribution networks engineers and system designers face multiple operational issues in delivering safe and clean potable water to their customers.
Although several monographs and reviews have appeared on individual polymers of this type, and their applications and other technical aspects have also been discussed, this is apparently the first book to deal with the physical chemistry of water-soluble synthetic polymers as a group. This collective survey enables their properties and behaviour to be compared, and to be correlated with their molecular structures for predictive purposes. However, this has made it necessary to critically re-appraise much of the earlier fundamental work, so that current discussion of more recent work can be put on ta proper basis. Thus, of the 1800 or so references cited, the middle two-thirds related to the twenty-year period centred on about 1968. Nevertheless, sufficient key recent references have also been included so that the existing 'state of the art is delineated.
Decision-Making in Water Resource Policy and Management: An Australian Perspective presents the latest information in developing new decision-making processes. Topics covered include key aspects of water resources planning, recent water resource policy changes in irrigation, urban, and environmental considerations, the evolution of a water market, a number of case studies that provide real examples of improved decision-making, transfer of the Australian experience overseas, and challenges for the future. Many countries are experiencing major water scarcity problems which will likely intensify with the continued impacts of climate change. In response to this challenge, there is increased worldwide focus on the development of more sustainable and integrated water resource policies. The Australian experience over the past three decades has led to major improvements in the decision-making processes in water resources policy and management, particularly in response to drought and climate change, providing a great model on which other nations can use and adapt. This information is essential to early to mid-career practitioners engaged in policy, planning and operational roles in all fields of water resource policy and management, and catchment management.
Water and energy are inextricably linked as unsound management of either resource can have an impact on the cost, availability, and sustainability of the other. This book explores the "energy for water" component of the water-energy nexus. It offers diverse case studies from around the world including the deserts of Saudi Arabia, rural China, Pakistan's Indus Basin, arid Greek islands, and urban centers such as Los Angeles. The analyses show that while many regions face unique water scarcity challenges, they are all united by the fact that solutions require mobilizing energy. This book focuses on how different policies and technologies are changing the way societies use energy to extract, treat, and transport water. In terms of policy, chapters explore how initiatives aimed at reducing demand for water and improved integrated resource planning can lead to energy savings. Regarding technology, case studies highlight the pros and cons of different methods of meeting water demand. Through exploring both technology and policy across a wide range of diverse case studies, the book offers a robust explanation of the "energy for water" side of the water-energy nexus equation, making it valuable reading for academics and policymakers. This book was originally published as a special issue as International Journal of Water Resources Development.
Water for the Environment: From Policy and Science to Implementation and Management provides a holistic view of environmental water management, offering clear links across disciplines that allow water managers to face mounting challenges. The book highlights current challenges and potential solutions, helping define the future direction for environmental water management. In addition, it includes a significant review of current literature and state of knowledge, providing a one-stop resource for environmental water managers.
Sealing of boreholes and underground excavations has not received much engineering attention until fairly recently. The growing awareness of and sensitivity to environmental concerns of the technical community as well as of the public at large has resulted in an increasing recognition of the fact that these geological penetrations may have an environmental impact. The issue of possible contamination resulting from migration along boreholes, adits, shafts or tunnels unquestionably has been raised most forcefully with in the context of nuclear waste disposal. Several nuclear waste disposal programs, notably the Civilian and the Defence programs of the US De partment of Energy, the US Nuclear Regulatory Commission and the Canadian and Swedish radioactive waste disposal programs have conducted major research efforts aimed at developing adequate seal designs for penet rations in host rock formations for high-level nuclear waste repositories. While a considerable data base has been gathered over the last two decades or so with regard to the performance of seals, most of the information is presented in research reports and widely scattered papers in journals and proceedings of conferences. Hence, the materials are not readily accessible to potential users such as designers, contractors or regulators who are not familiar with nuclear waste disposal programs."
Public agencies and industry will probably spend tens of billions of dollars on new water pollution abatement facilities in the next few decades. Added billions will be spent for the operation of new and existing facilities. How can physical science research reduce the cost of achieving objectives? And how can social science research make sure that the right objectives are being efficiently pursued? This title, first published in 1962, is directed to the orientation of the research effort, and the tool used for this purpose is an economic framework. This book will be of interest to students of economics and environmental studies.

Our interpretations of the world we live in, and the people and institutions that comprise it, are acquired through complex interactions among what we believe to be true, what the world is, and/or what others think it is. Understanding those complex interactions is one of the most important goals of the social sciences. Of the many disciplines that have contributed to that understanding, two take center stage in this book -- psychology and communication. This volume's purpose is to reconnect the partially isolated environments of social psychology and communication. To do so, it utilizes four building blocks: * the cognitive foundations of interpersonal communication as it might be studied from a social psychological perspective * insiders' views of interpersonal communication from a cognitive psychological standpoint * insiders' approaches to interpersonal communication from an AI perspective * a critique of the cognitive enterprise that reflects the strong philosophical grounding of communication. Overall, the chapters typify some of the most interesting cognitive work done in the study of interpersonal communication. As such, the book should promote productive dialogue across disciplinary boundaries and stimulate further work within the field of interpersonal communication.
The Llobregat belongs to the most thoroughly studied rivers in Europe and is a paradigm of the confluence of human and natural disturbances in a single basin. Because of its location in a very densely populated region and its Mediterranean character, the Llobregat supports a mixture of irregular flow, water abstraction, excess nutrients, mining debris, and a wide array of pollutants. The aquatic organisms strive to survive in a dramatically changing river that passes through a succession of dams, weirs and channels. The long-term river monitoring as well as the research that has been carried out in the river for a long time have provided an extensive knowledge of these disturbances and their effects on the biological communities. This book highlights the available information, with emphasis on the hydrological, chemical and biological elements interspersed in the river. Experts in the field discuss the main nutrient patterns and pollutant occurrence and the responses of the biological quality elements as well as the river ecosystem to the overall natural and man-made influences.
As pressures on water resources have increased, problems of water quality have claimed high priority in national concern and governmental policy. In this book, first published in 1969, Lyle E. Craine describes how Great Britain enacted new governmental procedures for studying, planning, and executing water management programmes. Although the physical and social characteristics of the United States' water resources problems differ from those of England, this analysis of the British institutional arrangements for water management suggests constructive insights for managing water resources within the individual states. This title is a valuable resource for students interested in environment and sustainability issues, national water resources problems, and government policy making.
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.

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.

In recent years the subject of pollution of natural waters by aquaculture has received considerable attention. With increasingly stringent regulation of wastewater quality from fish farms around the world, those involved in the industry need to be aware of the causes of pollution from fish and shellfish farms and of methods by which this pollution may be prevented. This book aims to bring the principles of wastewater treatment and other pollution control techniques for fish and shellfish farming to a wide audience of farmers, students, scientists and engineers; in fact anyone who works in aquaculture or pollution control. For this reason, the authors who have between them much experience in this area have written this important book with both the specialist and those new to the area in mind. As part of the growing Aquaculture Series, this title gives a comprehensive insight into this topic of vital importance to the aquaculture industry. This book should be on the shelves of all those involved in fish and shellfish farming and connected environmental issues, and available in universities and research establishments for students and professionals alike.
Closed circuit trickle irrigation is a form of micro irrigation that increases energy and water efficiency by using closed circuit drip irrigation systems designs. Modifications are made to traditional micro irrigation methods to reduce some of the problems and constraints, such as low compressor water at the end of irrigation lines. This approach has proved successful for the irrigation of fruit trees and some vegetable and field crops. Closed circuits of drip irrigation systems require about half of the water needed by sprinkler or surface irrigation. Lower operating pressures and flow rates result in reduced energy costs, and a higher degree of water control is attainable as well. Plants can be supplied with more precise amounts of water, and disease and insect damage is reduced because plant foliage stays dry. Fertilizers can also be applied through this type of system, which can result in a reduction of fertilizer and fertilizer costs. This new volume in the Research Advances in Sustainable Micro Irrigation book series presents a diverse collection of research on closed circuit irrigational technology and design and provides studies of its use on such crops as wheat, maize, yellow corn, soybeans, rice, and snap peas. The book explores: * Soil moisture and salinity distributions under modified sprinkler irrigation * Performance of sprinkler irrigation * Design considerations for closed circuit drip irrigation systems * Performance of bubbler irrigation * Energy and water savings of drip irrigation systems * Automation of mini-sprinkler and drip irrigation systems * Water and fertilizer use efficiencies for drip irrigated maize * Evaluation of emitter clogging for drip irrigated systems This book will be valuable for those interested in irrigation planning and management, namely, researchers, scientists, educators, upper-level students, agricultural extension services, and others.
Falling or stagnant agricultural growth, increasing dependence on groundwater, climate variability, swift industrialization, and unplanned and unregulated urbanization in South Asia have spawned a variety of challenges for water resources governance, management and use: groundwater overdraft; insufficient, ill-managed and poor-quality freshwater supply vis-a-vis escalating demand; and water pollution. Water policies in each of the South Asian countries thus call for a more holistic understanding for the efficient management, equitable distribution and sustainable use of this scarce resource. Analyzing the economic, demographic and ideological context in which water policies are framed and implemented, this book argues for an integrated framework in formulating and implementing water policies in South Asia. It also highlights some common missing links in the national policies: problems of techno-centric and blueprint approach to water management, growing influence of international donor agencies and inadequate concern for issues such as equity, sustainability, gender sensitivity, accountability, regional diversity in property rights regimes and water management practices, and regional conflicts over water access. The innovative and nuanced knowledge on water resources produced from detailed case studies in India, Bangladesh, Bhutan, Nepal, Pakistan and Sri Lanka will be useful for professionals, academics, policymakers and activists as well as those in development studies, environmental studies, natural resource management and public administration. |
