In the Pacific Northwest, the Snake River and its wilderness tributaries were as recently as a half century ago some of the world s greatest salmon rivers. Now, due to four federal dams, the salmon population has dropped close to extinction. Steven Hawley, journalist and self-proclaimed river rat, argues that the best hope for the Snake River lies in dam removal, a solution that pits the power companies and federal authorities against a collection of Indian tribes, farmers, fishermen, and river recreationists. The river s health, as he demonstrates, is closely connected to local economies,...

The book is based on the international conference River Conservation and Management:20 Years On held at York. Thirty-one chapters, with contributions from North and South...

Each chapter in the book has been specifically commissioned to represent areas in which recent progress has been made in the field. The topics covered also represent a coherent progression through the principal areas of the subject (hydraulics; sediment transport; river morphology; tools and methods; applications of...

Far from being the serene, natural streams of yore, modern rivers have been diverted, dammed, dumped in, and dried up, all in efforts to harness their power for human needs. But these rivers have also undergone environmental change. The old adage says you can t step in the same river twice, and Ellen Wohl would agree natural and synthetic change are so rapid on the world s great waterways that rivers are transforming and disappearing right before our eyes.

A World of Rivers explores the confluence of human and environmental change on ten of the great rivers of the world....

For sixty million years, the Gila River, longer than the Hudson and the Delaware combined, has shaped the ecology of the Southwest from its source in New Mexico to its confluence with the Colorado River in Arizona. Today, for at least half its length, the Gila is dead, like so many of the West's great rivers, owing to overgrazing, damming, and other practices. This richly documented cautionary tale narrates the Gila's natural and human history. Now updated, McNamee's study traces recent efforts to resuscitate portions of this important riparian corridor.

Filling a niche in the geomorphology teaching market, this introductory book is built around a 12 week course in fluvial geomorphology.

'Reading the landscape' entails making sense of what a riverscape looks like, how it works, how it has evolved over time, and how alterations to one part of a catchment may have secondary consequences elsewhere, over different timeframes. These place-based field analyses are framed within their topographic, climatic and environmental context. Issues and principles presented in the first part of this book provide foundational understandings...
