Virtual Rivers
"This book fills an important gap with a clear and comprehensive explanation of how rivers are changed by human activity. The book also includes a generous selection of striking historical and contemporary photographs, maps, and diagrams that provide a fresh perspective on the extent to which the rivers of the Colorado Front Range have undergone change during the last two centuries."--BOOK JACKET.
Of Rock and Rivers
This deeply personal collection of essays paints a progressive view of the American West as seen by a geologist. The author traces her twenty years of living and conducting research in the natural landscapes of the West as she investigates the conflict between environmental history and widely held romanticized views of the region.
Saving the Dammed
Saving the Dammed follows the course of the seasons throughout one representative year at a beaver meadow in Rocky Mountain National Park, Colorado. The seasonal changes provide a backdrop against which to explore how beavers change river valleys and how the decline in beaver populations has altered river ecosystems.
A World of Rivers
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. Ranging from the Murray-Darling in Australia and the Yellow River in China to Central Europe’s Danube and the Unit...
Disconnected Rivers
Ellen Wohl offers a survey of the history & present condition of river systems across the US. After describing the biological chemical & physical aspects of the functioning of rivers, she discusses the changes as the result of development & federal management, & examines rehabilitation projects.
Island of Grass
Island of Grass tells the story of the Cathy Fromme Prairie Natural Area, a 240-acre preserve surrounded by housing developments in Fort Collins, Colorado. This small grassland is a remnant of the once-vast prairies of the West that early European explorers and settlers described as seas of grass. Agricultural land use and urban expansion during the past two centuries have fragmented and altered these prairies. All that remains today are small islands. These remnants cannot support some of the larger animals that once roamed the prairie, but they continue to support a diverse array of plants and animals and can still teach us much about grassland ecology. Through her examinations of daily ch...
Sustaining River Ecosystems and Water Resources
This work is designed to broaden the scope with which many people regard a river. Rivers are commonly regarded from a very simplistic perspective as conduits for downstream flows of water. In this context, it may be considered acceptable and necessary to engineer the channel to either facilitate such flows (e.g., channelization, levees) or limit flows and store water (e.g., water supply reservoirs, flood control). The book presents the concept of a river as a spatially and temporally complex ecosystem that is likely to be disrupted in unexpected and damaging ways by direct river engineering and by human activities throughout a drainage basin. Viewing a river as a complex ecosystem with nonli...
Inland Flood Hazards
This edited volume was originally published in 2000 and presents a comprehensive, interdisciplinary review of issues related to inland flood hazards. It addresses physical controls on flooding, flood processes and effects, and responses to flooding, from the perspective of human, aquatic, and riparian communities. Individual chapter authors are recognized experts in their fields who draw on examples and case studies of inland flood hazards from around the world. This volume is unusual among treatments of flood hazards in that it addresses how the non-occurrence of floods, in association with flow regulation and other human manipulation of river systems, may create hazards for aquatic and riparian communities. This book will be a valuable resource for everyone associated with inland flood hazards: professionals in government and industry, and researchers and graduate students in civil engineering, geography, geology, hydrology, hydraulics, and ecology.
Large Rivers
Large Rivers: Geomorphology and Management explores an important topic in geomorphology and sedimentology: the form and function of major rivers. Our knowledge of the big rivers of the world is limited. It is currently difficult to recognise large rivers of the past from relict sedimentary deposits or to structure management policies for long international rivers. This exciting book brings together a set of papers on large rivers of the world, as a unique introduction to a demanding subject. The book includes thirty chapters and is organised into three sections. The first part is on the environmental requirements for creating and maintaining a major river system. The second is a collection o...
