Entirely updated in the light of the recent World Commission on Dams Report, and responding to it, this new edition of Patrick McCully's now classic study shows why large dams have become such a controversial technology in both industrialized and developing countries. The book explains the history and politics of dam building worldwide and shows why large dams have become so controversial. It details the ecological and human impacts of large dams, and shows how the 'national interest' argument is used to legitimize uneconomic and unjust projects which benefit elites while impoverishing tens of millions, describes the technical, safety and economic problems of dam technology, the structure of the international dam-building industry, and the role played by international banks and aid agencies. It tells the story of the rapid growth of the international anti-dam movement, and recounts some of the most important anti-dam campaigns around the world. McCully shows how the dam lobby and governments have reacted to criticism by cosmetic 'greening' of the dam-building process, and through state repression outlines the alternatives to dams, and argues that their replacement by less destructive alternatives requires the opening up of the industry's practices to public scrutiny.

Dam removal wasn't a realistic option in the twentieth century, and people who suggested it were dismissed as fringe environmentalists. Over the past twenty years, dam removal has become increasingly common, with dozens of removals now taking place each year in the US. Same River Twice tells the stories of three major Northwestern dam removals - the politics, people, hopes, and fears that shaped three rivers and their communities. Brewitt begins each story with the dam's construction, shows how its critics gained power, details the conflicts and controversies of removal, and explores the aftermath as the river re-established itself.

Dams & river regulation have become an integral part of 20th-century landscape & livelihood. Virtually every river in the lower 48 states is now regulated by dams, locks, or diversions. This report illustrates the downstream consequences of dams & explains the basis on which rivers can be scientifically managed. Following a look at a free-flowing river -- the upper Salt River of Arizona -- & its natural cycles of flow & sediment, 6 regulated rivers are examined. Each of these rivers -- the Snake, Rio Grande, Chattahoochee, Platte, Green & Colorado -- highlights a particular use of a dam or a particular downstream effect.

This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

Explores the story of Federal contributions to dam planning, design, and construction.

The conventional approach to river protection has focused on water quality and maintaining some "minimum" flow that was thought necessary to ensure the viability of a river. In recent years, however, scientific research has underscored the idea that the ecological health of a river system depends not on a minimum amount of water at any one time but on the naturally variable quantity and timing of flows throughout the year. In Rivers for Life, leading water experts Sandra Postel and Brian Richter explain why restoring and preserving more natural river flows are key to sustaining freshwater biodiversity and healthy river systems, and describe innovative policies, scientific approaches, and management reforms for achieving those goals. Sandra Postel and Brian Richter: explain the value of healthy rivers to human and ecosystem health; describe the ecological processes that support river ecosystems and how they have been disrupted by dams, diversions, and other alterations; consider the scientific basis for determining how much water a river needs; examine new management paradigms focused on restoring flow patterns and sustaining ecological health; assess the policy options available for managing rivers and other freshwater systems; explore building blocks for better river governance. Sandra Postel and Brian Richter offer case studies of river management from the United States (the San Pedro, Green, and Missouri), Australia (the Brisbane), and South Africa (the Sabie), along with numerous examples of new and innovative policy approaches that are being implemented in those and other countries. Rivers for Life presents a global perspective on the challenges of managing water for people and nature, with a concise yet comprehensive overview of the relevant science, policy, and management issues. It presents exciting and inspirational information for anyone concerned with water policy, planning and management, river conservation, freshwater biodiversity, or related topics.
