Outlines the role of science in restoring or otherwise altering unwanted downstream effects of dams, including eroding river banks, changes in waterfowl habitat, threats to safe recreational use, and the loss of river sand bars, examining seven selected areas of the country -- the upper Salt River in central Arizona; the Snake River in Idaho, Oregon and Washington; the Rio Grande in New Mexico and Texas; the Chattahoochee River in Georgia; the Platte River in Wyoming, Colorado and Nebraska; the Green River in Utah; and the Colorado River in Arizona -- to focus on specific downstream effects of dams and the management issues related to their operation.
This text explores the natural history of Texas and more than 2900 springs in 183 Texas counties. It also includes an in-depth discussion of the general characteristics of springs - their physical and prehistoric settings, their historical significance, and their associated flora and fauna.
In a world facing a growing water crisis, conflicts regarding water sharing and environmental issues are expected to grow, especially in transboundary river basins, where 40% of the world's population lives. This book represents one of the first attempts to bring together methodologies and analytical tools from socio-economic, international policy, engineering, and water management specialists dealing with transboundary water resources. The book is divided into three parts. Part I introduces state--of-the-art concepts in institutional policy and conflict analysis. Part II presents engineering approaches and models for transboundary water management and conflict resolution. Part III analyzes cases in international river basins and enclosed seas.
Interdisciplinary volume considers how nine arid/semi-arid river basins with irrigated agriculture will survive future climate change, siltation, and decreased flow.
One of the most controversial issues of the water sector in recent years has been the impacts of large dams. Proponents have claimed that such structures are essential to meet the increasing water demands of the world and that their overall societal benefits far outweight the costs. In contrast, the opponents claim that social and environmental costs of large dams far exceed their benefits, and that the era of construction of large dams is over. A major reason as to why there is no consensus on the overall benefits of large dams is because objective, authoritative and comprehensive evaluations of their impacts, especially ten or more years after their construction, are conspicuous by their absence. This book debates impartially, comprehensively and objectively, the positive and negative impacts of large dams based on facts, figures and authoritative analyses. These in-depth case studies are expected to promote a healthy and balanced debate on the needs, impacts and relevance of large dams, with case studies from Africa, Asia, Australia, Europe and Latin America.
