In this comprehensive treatment of the major rivers of the world, author James R. Penn's purpose is not just to feature geographic data, but to tell a story of historical drama, poetic significance, and cultural relationships. The book shows glimpses of Chairman Mao boosting his image by swimming in the Yangtze; Indian middlemen residing on both sides of the Columbia River exacting tolls from travelers like Lewis and Clark; and, near the Dordogne in southwest France, Paleolithic cave art, paintings, and designs in rock shelters and subterranean caverns, which are textbook examples of early...

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....

Here, Ken Lamberton finds his way through a lifetime of exploring southern Arizona's Santa Cruz River. This river--dry, still, and silent one moment, a thundering torrent of mud the next--serves as a reflection of the desert around it: a hint of water on parched sand, a path to redemption across a thirsty landscape.

With his latest book, Lamberton takes us on a trek across the land of three nations--the United States, Mexico, and the Tohono O'odham Nation--as he...

Janisse Ray was a babe in arms when a boat of her father's construction cracked open and went down in the mighty Altamaha River. Tucked in a life preserver, she washed onto a sandbar as the craft sank from view. That first baptism began a lifelong relationship with a stunning and powerful river that almost nobody knows.

The Altamaha rises dark and mysterious in southeast Georgia. It is deep and wide bordered by swamps. Its corridor contains an extraordinary biodi-versity, including many rare and endangered species, which led the Nature Conservancy to designate it as one of the...

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...

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.
