An integrated framework for water resources management It has been said that "water is the next oil." A strong global consensus has begun to develop that effective water management must start at the watershed level, and that water management actions must be taken in the context of watersheds, and the human communities in them. Integrated Watershed Management: Principles and Practice, Second Edition presents a flexible, integrated framework for watershed management that addresses the biophysical, social, and economic issues affecting water resources and their use. Comprehensive in scope and multidisciplinary in approach, it equips readers with the necessary tools and techniques to develop sound watershed management policy and practice—from problem definition and goal setting to selecting management strategies and procedures for monitoring implementation. Ten years of practice have demonstrated that the core concepts presented in the first edition of this book remain true and important. This Second Edition is fully updated to reflect current practice and recent experience in watershed management, including: New coverage of strategies for the selection and evaluation of public engagement processes Sampling, data management, and computer simulation technologies Recent legislative changes International watershed issues Many new case studies Water resources planning and management is not just a technical challenge; it is also a social challenge, and an opportunity. It is, ultimately, a framework for human societies to shape, protect, and improve the environment in which they live. Providing a rational framework for the development of water resources management strategies, Integrated Watershed Management, Second Edition is a one-stop resource for upper-level students and professionals in environmental science, natural resource management, and environmental engineering.

Conceptual separation of humans and natural ecosystems is reflected in the thinking of most natural resource management professions, including for estry, wildlife management, fisheries, range management, and watershed management (Burch 1971). Such thinking can deny the reality of the human element in local, regional, and global ecosystems (Bonnicksen and Lee 1982, Klausner 1971, Vayda 1977). As complex organisms with highly developed cultural abilities to modify their environment, humans directly or indirectly affect almost all terrestrial and aquatic ecosystems (Bennett 1976). Conse quently, information for managing watershed ecosystems is incomplete without consideration of human institutions and activities. Sociologists have studied the relationships between human societies and the land base or ecosystems on which they depend for over 60 years (Field and Burch 1990). These studies are distinguished by (1) a holistic perspec tive that sees people and their environments as interacting systems, (2) flex ible approaches that permit either the environment or human society to be treated as the independent variable in analyzing of society-environment re lations, and (3) accumulation of a substantial body of knowledge about how the future welfare of a society is influenced by its uses (or misuses) of land and water (Firey 1990).

In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading.

Land use and water resources are two major environmental issues which necessitate conservation, management, and maintenance practices through the use of various engineering techniques. Water scientists and environmental engineers must address the various aspects of flood control, soil conservation, rainfall-runoff processes, and groundwater hydrology. Watershed Management and Applications of AI provides the necessary principles of hydrology to provide practical strategies useful for the planning, design, and management of watersheds. The book also synthesizes novel new approaches, such as hydrological applications of machine learning using neural networks to predict runoff and using artificial intelligence for the prediction of groundwater fluctuations. Features: Presents hydrologic analysis and design along with soil conservation practices through proper watershed management techniques Provides analysis of land erosion and sediment transport in watersheds from small to large scale Includes estimations for runoff using different methodologies with systematic approaches for each Discusses water harvesting and development of water yield catchments This book will be a valuable resource for students in hydrology courses, environmental consultants, water resource engineers, and researchers in related water science and engineering fields.

If you work in the water quality management field, you know the challenges of monitoring and controlling pollutants in our water supply. The increasing problem of agricultural nonpoint source pollution requires complex solutions. Agricultural Nonpoint Source Pollution: Watershed Management and Hydrology covers the latest techniques and methods of managing large watershed areas, with an emphasis on controlling non-point source pollution, especially from agricultural run-off. Written by leading experts, the book includes topics such as: nitrate and phosphorus pollution, pesticide contamination, erosion and sedimentation, water-table management, and watershed management. The authors discuss the effects of agricultural run-off - one of the most intransigent problems now faced by environmental engineers and hydrologists. They explore each issue with an eye towards the integrated management of water quality and water resources over a defined area or region. This single-source reference gives you a complete understanding of the whats, whys, and hows of nonpoint source pollution - and more importantly of how to monitor and manage it. Agricultural Nonpoint Source Pollution: Watershed Management and Hydrology provides a broad but detailed overview that helps you to comprehend the intricacies of the problem and puts you on the path to finding the answers.

A radical new approach to tackling the growing threat of water scarcity Water is essential to life, yet humankind’s relationship with water is complex. For millennia, we have perceived it as abundant and easily accessible. But water shortages are fast becoming a persistent reality for all nations, rich and poor. With demand outstripping supply, a global water crisis is imminent. In this trenchant critique of current water policies and practices, Edward Barbier argues that our water crisis is as much a failure of water management as it is a result of scarcity. Outdated governance structures and institutions, combined with continual underpricing, have perpetuated the overuse and undervaluation of water and disincentivized much-needed technological innovation. As a result “water grabbing” is on the rise, and cooperation to resolve these disputes is increasingly fraught. Barbier draws on evidence from countries across the globe to show the scale of the problem, and outlines the policy and management solutions needed to avert this crisis.

Covers the watershed approach to managing water resources in a sustainable fashion with case studies to show how the concept of watershed management is being implemented. Modelling is used to show how systems can be successfully managed in the future. Useful for students on water supply and management courses as well as those already in the field.

Watershed management is an integrated approach that evaluates system-wide implications of natural resource problems. It has received considerable attention among communities and resource managers as an appropriate approach to deal with complex problems. Problem-solving is an important aspect of watersheds that involves diagnosis, assessment, solution, and implementation issues that often mean processing an enormous amount of information. A typical problem requires compilation of information from a variety of sources and is time consuming. This book will use a problem-based approach to present information on each problem facing watersheds. The subject area derives from a variety of disciplines and experiences and is presented clear and systematically throughout for easy reading and understanding. The problems covered in the book are major ones facing watersheds through the globe. The first chapter introduces principles of watershed management and is followed by chapters that are problem specific. Each problem is dealt with systematically with introduction, analysis, strategies, and further references. Watershed Management provides a valuable reference to professionals, students, scientists, and common citizens who are interested in learning about the variety of problems and approaches in watershed management.

In recent years, water resource management in the United States has begun a shift away from top-down, government agency-directed decision processes toward a collaborative approach of negotiation and problem solving. Rather than focusing on specific pollution sources or specific areas within a watershed, this new process considers the watershed as a whole, seeking solutions to an interrelated set of social, economic, and environmental problems. Decision making involves face-to-face negotiations among a variety of stakeholders, including federal, state, and local agencies, landowners, environmentalists, industries, and researchers. Swimming Upstream analyzes the collaborative approach by providing a historical overview of watershed management in the United States and a normative and empirical conceptual framework for understanding and evaluating the process. The bulk of the book looks at a variety of collaborative watershed planning projects across the country. It first examines the applications of relatively short-term collaborative strategies in Oklahoma and Texas, exploring issues of trust and legitimacy. It then analyzes factors affecting the success of relatively long-term collaborative partnerships in the National Estuary Program and in 76 watersheds in Washington and California. Bringing analytical rigor to a field that has been dominated by practitioners' descriptive accounts, Swimming Upstream makes a vital contribution to public policy, public administration, and environmental management.

Coastal watersheds differ from others by their unique features, including proximity to the ocean, weather and rainfall patterns, subsurface features, and land covers. Land use changes and competing needs for valuable water and land resources are especially more distinctive to such watersheds. This book covers recent research relevant to coastal watersheds. It addresses the impact of a stream’s chemical, biological, and sediment pollutants on the quality of the receiving waters, such as estuaries, bays, and near-shore waters. The contents of the book can be divided into three sections; a) overview of hydrological modelling, b) water quality assessment, and c) watershed management. This book differs from other hydrology books by dealing with coastal watersheds which are characterized by their unique features: including weather and rainfall patterns, subsurface characteristics, and land use and cover. In addition to academia, the book should be of interest to organizations concerned with watershed management, such as local and federal governments and environmental groups. Overall, the book is expected to satisfy a great need toward understanding and managing critical areas in many parts of the world.
