The politics of building dams and levees and other structures are just part of the policies determining how American rivers are managed or mismanaged. America's well-being depends upon the health of those rivers and important decisions go beyond just dam-building or dam removal. American rivers are suffering from poor water quality, altered flows, and diminished natural habitat. Current efforts by policymakers to change the ways American rivers are managed range from the removal of dams to the simulation of seasonal flows to the restoration of habitat, all with varying degrees of success. Efforts to restore American rivers are clearly delineated by William Lowry in Dam Politics as he looks at how public policy and rivers interact, examines the physical differences in rivers that affect policies, and analyzes the political differences among the groups that use them. He argues that we are indeed moving into an era of restoration (defined in part as removing dams but also as restoring the water quality, seasonal flows, and natural habitat that existed before structural changes to the rivers), and seeks to understand the political circumstances that affect the degree of restoration. Lowry presents case studies of eight river restoration efforts, including dam removals on the Neuse and Kennebec rivers, simulation of seasonal flows on the Colorado river, and the failed attempt to restore salmon runs on the Snake river. He develops a typology of four different kinds of possible change--dependent on the parties involved and the physical complexity of the river--and then examines the cases using natural historical material along with dozens of interviews with key policymakers. Policy approaches such as conjunctive water management, adaptive management, alternative licensing processes, and water marketing are presented as possible ways of using our rivers more wisely. Dam Politics provides a useful and systematic account of how American waterways are managed and how current policies are changing. American rivers are literally the lifeblood of our nation. Lowry has written a lively and accessible book that makes it clear as a mountain stream that it matters deeply how those rivers are managed.
There are many people and places connected to rivers: fishermen whose livelihood depends on river ecosystems, farms that need irrigation, indigenous groups whose cultures rely on fish and flowing waters, cities whose electricity comes from hydroelectric dams, and citizens who seek wild nature. For all of these people, instream flow is vitally important to where and how they live and work. Riverflow reveals the diverse and creative ways people are using the law to restore rivers, from the Columbia, Colorado, Klamath and Sacramento-San Joaquin watersheds in America, to the watersheds of the Tweed in England and Scotland, the Fraser in Canada, the Saru in Japan, the Nile in North Africa, and the Tigris-Euphrates in the Middle East. Riverflow documents that we already have the legal tools to preserve the ecological integrity of our waterways; the question is whether we have the political will to deploy these tools effectively.
This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.
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.
Written by civil engineers, dam safety officials, dam owners, geologists, hydraulic engineers, and risk analysts, this handbook is the first cooperative attempt to provide practical solutions to dam problems within the financial constraints faced by dam owners. It provides hands-on information for identifying and remedying common defects in concrete and masonry dams, embankment dams, reservoirs, and related structures. It also includes procedures for monitoring dams and collecting and analyzing data. Case histories demonstrate economical solutions to specific problems.
If changed by development, the authors found the present Osage valley landscape expressive. Illustrated with hundreds of color photographs, period maps, and vintage images, this book tells the dramatic saga of human ambition pitted against natural limitations and forces beyond man's control.
Explores the story of Federal contributions to dam planning, design, and construction.
Journalist, filmmaker, and environmental activist Ben Raines turns his attention to Alabama's Tensaw Delta in this gorgeously illustrated and meticulously researched book. Identified by Raines and others as America's own Amazon, the Tensaw Delta is the most biodiverse ecosystem in our nation. This special book celebrates this most significant of Alabama's waterways while also chronicling how it is increasingly at risk.
