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...

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...

The culmination of ten years of research and observation, McCool's book confirms the surprising news that America's rivers are indeed returning to a healthier, free-flowing condition. The politics of river restoration...

In Goodbye to a River, John Graves defined what it means to know a river--as a real place, as a landscape of memory and imagination, and as "a piece of country, that] hunted and fished and roamed over, felt and remembered, can be company enough." Readers who've taken the canoe trip down the Brazos with him have long wished to travel other rivers with John Graves. Those journeys now begin in Texas Rivers.

This book marries the work of two Texas legends. John Graves brings to Texas Rivers his ability to weave history, geography, and culture...

In the Pacific Northwest, the river of dominance is the Columbia, and in ways both profound and mundane its history is the history of the region. In Great River of the West historians and anthropologists consider a range of topics about the river, from Indian rock art, Chinook Jargon, and ethnobotany on the Columbia to literary and family history, the creation of an engineered river, and the inherent mythic power of place.

Since first contact between Euro-Americans and Native peoples during the late 18th century, the river's history has been characterized by dramatic...
