Produced biennially, The World’s Water provides a timely examination of the key issues surrounding freshwater resources and their use. Each new volume identifies and explains the most significant trends worldwide, and offers the best data available on a variety of topics related to water. The 2008-2009 volume features overview chapters on: • water and climate change • water in China • status of the Millennium Development Goals for water • peak water • efficient urban water use • business reporting on water This new volume contains an updated chronology of global conflicts associated with water, as well as brief reviews of issues regarding desalination, the Salton Sea, and the Three Gorges Dam. From the world’s leading authority on water issues, The World’s Water is the most comprehensive and up-to-date source of information and analysis on freshwater resources and the political, economic, scientific, and technological issues associated with them. It is an essential reference for water resource professionals in government agencies and nongovernmental organizations, researchers, students, and anyone concerned with water and its use.

The Three Gorges dam, currently being constructed on the Yantgze River in China, is controversial both inside and outside China, particularly because of the large number of people to be resettled (officially 1.2 million) and the environmental impacts. Using material previously unavailable in any Western language, it analyses the Chinese discussions over policy-making for the resettlement process and impacts. It concludes that the environment and resettlement policies have been linked in a new way in this project. However, despite these positive developments, it argues that the social impacts from resettlement have not yet reached a high level of political attention and that the Chinese authorities need to acknowledge that resettlement has social costs. The book provides an understanding of the social, political and economic factors of one of the largest and most controversial development projects currently being implemented. It also sheds light on China's policy-making procedures and political priorities over the past decade.

This volume translates crucial Chinese documents on a debate currently raging in China on a proposed project that has enormous implications for its environmental, economic, and social impact - the Three Gorges (Sanxia) Project on the Yangtze River. The most massive water resource project ever planned in China and one of the largest in the world, the Three Gorges Project would cost $1.1 billion to build, would necessitate the relocation of 1.1 million people, would flood a 375-mile-long area and thus destroy some of China's - indeed the world's - most beautiful scenery, and would threaten the extinction of a rare river porpoise. The editors seek to place the arguments in a clear and scholarly perspective that helps to make this book a valuable source of information.

Research on reservoir sedimentation in recent years has been aimed mainly at water resources projects in developing countries. These countries, especially in Africa, often have to cope with long droughts, flash floods and severe erosion problems. Large reservoir capacities are required to capture water provided by flash floods so as to ensure the supply of water in periods of drought. The problem arising however is that these floods, due to their tremendous stream power, carry enormous volumes of sediment which, due to the size of reservoirs, are virtually deposited in toto in the reservoir basin, leading to fast deterioration of a costly investment. Accurate forecasting of reservoir behaviour is therefore of the utmost importance.This book fills a gap in current literature by providing in one volume comprehensive coverage of techniques required to practically investigate the effects sediment deposition in reservoirs has on the viability of water resources projects. Current techniques for practically estimating sediment yield from catchments, estimating the volume of sediment expected to deposit in reservoirs, predicting sediment distribution and calculating scour downstream of reservoirs are evaluated and presented. The liberal use of diagrams and graphs to explain the various techniques enhances understanding and makes practical application simple. A major feature of the book is the application of stream power theory to explain the process of reservoir sedimentation and to develop four new methods for predicting sediment distribution in reservoirs.The book is primarily directed at practising engineers involved in the planning and design of water resources projects and at post-graduate students interested in this field of study.
