Proper management of water resources can take many forms, and requires the knowledge and expertise to work at the intersection of mathematics, geology, biology, geography, meteorology, political science, and even psychology. This book provides an essential foundation in water management and development concepts and practices, dissecting complex topics into short, understandable explanations that spark true interest in the field. Approaching the study of water resources systematically, the discussion begins with historical perspective before moving on to physical processes, engineering, water chemistry, government regulation, environmental issues, global conflict, and more. Now in its fourth edition, this text provides the most current introduction to a field that is becoming ever more critical as climate change begins to threaten water supplies around the world. As geography, climate, population growth, and technology collide, effective resource management must include a comprehensive understanding of how these forces intermingle and come to life in the water so critical to us all.
Sustainable Water Resource Development and Management is a comprehensive volume on this important topic. It broadly covers the sources, availability, demand, and supply of water and its uses in irrigation and crop production in agriculture. It then delves into many specific aspects of water resource development and management, including Irrigation creation and utilization Water storage efficiency, conveyance efficiency, distribution efficiency, and application efficiency The role of water in plant systems and soil-water-plant relationships Estimating the water need for irrigation along with management strategies Water quality in agriculture as well as the impact of water quality on human health Water pricing Wetland management and water productivity Water pollution in agriculture and water contamination in urban and rural areas Examples and case studies are included to illustrate and reinforce the text, such as reviews of river linking projects, adopted water management technologies for agricultural farms, important irrigation projects (both minor and major), and more.Written by two eminent researchers and scientists in agricultural water management, this informative volume is designed for students of agriculture, researchers, policymakers, and teachers engaged in the field of water management.
Better water management will be crucial if we are to meet many of the key challenges of this century - feeding the worlds growing population and reducing poverty, meeting water and sanitation needs, protecting vital ecosystems, all while adapting to climate change. The approach known as Integrated Water Resources Management (IWRM) is widely recognized as the best way forward, but is poorly understood, even within the water sector. Since a core IWRM principle is that good water management must involve the water users, the understanding and involvement of other sectors is critical for success. There is thus an urgent need for practical guidance, for both water and development professionals, based on real world examples, rather than theoretical constructs. That is what this book provides. Using case studies, the book illustrates how better water management, guided by the IWRM approach, has helped to meet a wide range of sustainable development goals. It does this by considering practical examples, looking at how IWRM has contributed, at different scales, from very local, village-level experiences to reforms at national level and beyond to cases involving trans-boundary river basins. Using these on-the-ground experiences, from both developed and developing countries in five continents, the book provides candid and practical lessons for policy-makers, donors, and water and development practitioners worldwide, looking at how IWRM principles were applied, what worked, and, equally important, what didn‘t work, and why.

Sustainable Water Resources Management presents the most current thinking on the environmental, social, and political dimensions of sustainably managing the water supply at local, regional, or basin levels.
This is the first book to authoritatively assess how water management will be shaped by 2020 due to forces within and outside the water sector. It offers a pragmatic assessment arrived at by experts from different parts of the world and different fields.
This book is open access under a CC BY-NC 4.0 license. This revised, updated textbook presents a systems approach to the planning, management, and operation of water resources infrastructure in the environment. Previously published in 2005 by UNESCO and Deltares (Delft Hydraulics at the time), this new edition, written again with contributions from Jery R. Stedinger, Jozef P. M. Dijkman, and Monique T. Villars, is aimed equally at students and professionals. It introduces readers to the concept of viewing issues involving water resources as a system of multiple interacting components and scales. It offers guidelines for initiating and carrying out water resource system planning and management projects. It introduces alternative optimization, simulation, and statistical methods useful for project identification, design, siting, operation and evaluation and for studying post-planning issues. The authors cover both basin-wide and urban water issues and present ways of identifying and evaluating alternatives for addressing multiple-purpose and multi-objective water quantity and quality management challenges. Reinforced with cases studies, exercises, and media supplements throughout, the text is ideal for upper-level undergraduate and graduate courses in water resource planning and management as well as for practicing planners and engineers in the field.
Freshwater management challenges are increasingly common. Allocation of limited water resources between agricultural, municipal and environmental uses now requires the full integration of supply, demand, water quality and ecological considerations. Water is the scarcest resource. The importance of the resource for the survival of the modern society - sustaining agricultural and industrial growth, and the retardation of environmental degradation needs no elaboration. Sustainable development and management of the resource require scientific and systematic approaches. This book covers the major aspects of water resources development and management such as the assessment of such resources, estimation of groundwater recharge, water-well construction and groundwater hydraulics, management of the resources, water contamination, protection of the resources, economics in water resources, statistical methods in water resources, and use of models in water resource management. When necessary, workout problems are provided to explain the application of theory/methodology in practice. This comprehensive and compact presentation of the book will serve as a textbook for undergraduate students in Civil Engineering, Environmental Engineering, Agricultural Engineering, Water Resources Engineering, and Geotechnical/Geo-science Engineering. Students of other relevant branches such as Hydrology, Geology, Hydrogeology, Geochemistry, Bio-Science Engineering, and engineers working in the field and at research institutes will also benefit from the lessons within its pages. Although the target audience of the book is undergraduate students, post-graduate students will also learn from this book. Considering the topics and depth covered, engineers, scientists, practitioners, and educators will find this book a valuable resource as well.
This study takes stock of the current water resources management in Armenia, including diagnosing the main sub-sectors (agriculture, urban, environment, and energy), reviewing the institutional framework and implementation status of water-sector policies, identifying the main challenges and making recommendations on the next steps.
Sub-Saharan Africa, the poorest region worldwide, has only recently begun to fully address the issues of meeting the water needs of its rapidly growing population, to reduce the deepening poverty besetting the region and to accelerate economic growth. The Nile Basin, characterized by sharp spatial and temporal variations in water resources and including countries with different economies, social and political structures and capacities, illustrates the challenges of developing and managing the waters of the Nile River and its tributaries, lakes and wetlands equitably among its 10 riparian countries. Ethiopia, the major source of the Nile but one of the poorest countries in the Nile Basin, has recently begun to implement plans to harness more Nile water through hydroelectric and irrigation development both for national use and for transboundary development as part of the Nile Basin Initiative. The Ethiopian government and communities, by using different management approaches and resources, are trying to boost water, energy and food production, strengthen conservation efforts and mitigate potential repercussions of water resources development. These initiatives and programs have not been comprehensively examined. In this study, the editors address these and other issues surrounding water resources management in all economic and water sectors in Ethiopia within the setting of the Nile Basin, the first comprehensive treatment of this subject. The wide scope of this book is consistent with the tenets of integrated water resources management, which demand that all water uses be managed in an integrated fashion for optimum and sustainable benefits to all water users, both humans and ecosystems. This book reveals the impacts of various resource management approaches and practices in Ethiopia and the Nile Basin. Specifically, it examines how deforestation and prevailing land use practices have exacerbated soil aridity and flood events, why irrigated agriculture and hydropower development have caused floodplain degradation, livelihood hardships and water-related diseases, where industrial and agricultural development is increasingly polluting water resources, how household water supplies can be obtained through rainwater harvesting and the dependence on hydropower reduced through alternative energy sources and how misguided government policies have impeded efforts to deal with these and other challenges. Results reveal dynamic interrelationships between these processes and identify the human and environmental driving forces, which must be understood in effective integrated water resources management. Another unique contribution of this book is the examination of the role of government and communities in managing water resources in Ethiopia. Results show that the top-down approach used by the socialist Derg government in soil and water conservation and social programs exacerbated water problems and reduced community participation. Moreover, the failure of its economic program reduced agricultural production, increasing dependency on relief food and further impeding community initiatives in soil and water conservation activities. Many elements of central planning persist in spite of the decentralization drive by the current government, but there is evidence that integration of the top-down and bottom-up approaches to water resources management is necessary (and feasible) to strengthen and up-scale programs to the national level. The book identifies a number of customary water and soil management practices and institutions that may strengthen especially community-based rainwater harvesting, small-scale irrigation, reforestation, soil and water conservation and flood control efforts. This is an important book for researchers and students of resources management, rural development, hydrology and African studies.
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. - Summarizes key results from three decades of changes in Australian water resource policy - Illustrates how Australian knowledge is being used in other countries and how this might be expanded - Provides international practitioners with real examples of where and how the Australian knowledge is assisting in other situations
