Book excerpt: CLICK HERE to download the first chapter from Elwha: A River Reborn (Provide us with a little information and we'll send your download directly to your inbox) A compelling exploration of one of the largest dam removal projects in the world—and the efforts to save a stunning Northwest ecosystem * Co-published with The Seattle Times * 125 color photographs, including rare historic images * Dam removal started in September 2011 while restoration work continues today In the fall of 2011, the Times was on hand when a Montana contractor removed the first pieces from two concrete dams on the Elwha River which cuts through the Olympic range. It was the beginning of the largest dam removal project ever undertaken in North America—one dam was 200 feet tall—and the start of an unprecedented attempt to restore an entire ecosystem. More than 70 miles of the Elwha and its tributaries course from the mountain headwaters to clamming beaches on the Strait of Juan de Fuca. Through interviews, field work, archival and historical research, and photojournalism, The Seattle Times has explored and reported on the dam removal, the Elwha ecosystem, its industrialization, and now its renewal. Elwha: A River Reborn is based on these feature articles. Richly illustrated with stunning photographs, as well as historic images, graphics, and a map, Elwha tells the interwoven stories of this region. Meet the Lower Elwha Klallam tribe, who anxiously await the return of renowned salmon runs savored over the generations in the stories of their elders. Discover the biologists and engineers who are bringing the dams down and laying the plan for renewal, including an unprecedented revegetation effort that will eventually cover more than 700 acres of mudflats. When the dam started to come down in Fall 2011—anticipated for more than 20 years since Congress passed the Elwha Restoration Act—it was the beginning of a $350 million project observed around the world. Elwha: A River Reborn is inspiring and instructive, a triumphant story of place, people, and environment striving to come together.

Download or read book Same River Twice written by Peter Brewitt and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dam removal wasn't a realistic option in the twentieth century, and people who suggested it were dismissed as fringe environmentalists. Over the past twenty years, dam removal has become increasingly common, with dozens of removals now taking place each year in the US. Same River Twice tells the stories of three major Northwestern dam removals - the politics, people, hopes, and fears that shaped three rivers and their communities. Brewitt begins each story with the dam's construction, shows how its critics gained power, details the conflicts and controversies of removal, and explores the aftermath as the river re-established itself.

Download or read book Concrete Revolution written by Christopher Sneddon and published by University of Chicago Press. This book was released on 2015-09-25 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water may seem innocuous, but as a universal necessity, it inevitably intersects with politics when it comes to acquisition, control, and associated technologies. While we know a great deal about the socioecological costs and benefits of modern dams, we know far less about their political origins and ramifications. In Concrete Revolution, Christopher Sneddon offers a corrective: a compelling historical account of the US Bureau of Reclamation’s contributions to dam technology, Cold War politics, and the social and environmental adversity perpetuated by the US government in its pursuit of economic growth and geopolitical power. Founded in 1902, the Bureau became enmeshed in the US State Department’s push for geopolitical power following World War II, a response to the Soviet Union’s increasing global sway. By offering technical and water resource management advice to the world’s underdeveloped regions, the Bureau found that it could not only provide them with economic assistance and the United States with investment opportunities, but also forge alliances and shore up a country’s global standing in the face of burgeoning communist influence. Drawing on a number of international case studies—from the Bureau’s early forays into overseas development and the launch of its Foreign Activities Office in 1950 to the Blue Nile investigation in Ethiopia—Concrete Revolution offers insights into this historic damming boom, with vital implications for the present. If, Sneddon argues, we can understand dams as both technical and political objects rather than instruments of impartial science, we can better participate in current debates about large dams and river basin planning.

Download or read book Environmental Flow Assessment written by John G. Williams and published by John Wiley & Sons. This book was released on 2019-06-10 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides critiques of current practices for environmental flow assessment and shows how they can be improved, using case studies. In Environmental Flow Assessment: Methods and Applications, four leading experts critique methods used to manage flows in regulated streams and rivers to balance environmental (instream) and out-of-stream uses of water. Intended for managers as well as practitioners, the book dissects the shortcomings of commonly used approaches, and offers practical advice for selecting and implementing better ones. The authors argue that methods for environmental flow assessment (EFA) can be defensible as well as practicable only if they squarely address uncertainty, and provide guidance for doing so. Introductory chapters describe the scientific and social reasons that EFA is hard, and provide a brief history. Because management of regulated streams starts with understanding freshwater ecosystems, Environmental Flow Assessment: Methods and Applications includes chapters on flow and organisms in streams. The following chapters assess standard and emerging methods, how they should be tested, and how they should (or should not) be applied. The book concludes with practical recommendations for implementing environmental flow assessment. Describes historical and recent trends in environmental flow assessment Directly addresses practical difficulties with applying a scientifically informed approach in contentious circumstances Serves as an effective introduction to the relevant literature, with many references to articles in related scientific fields Pays close attention to statistical issues such as sampling, estimation of statistical uncertainty, and model selection Includes recommendations for methods and approaches Examines how methods have been tested in the past and shows how they should be tested today and in the future Environmental Flow Assessment: Methods and Applications is an excellent book for biologists and specialists in allied fields such as engineering, ecology, fluvial geomorphology, environmental planning, landscape architecture, along with river managers and decision makers.

Download or read book Riverine Ecosystem Management written by Stefan Schmutz and published by Springer. This book was released on 2018-05-08 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Deep Water written by Jacques Leslie and published by Farrar, Straus and Giroux. This book was released on 2007-05-15 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: "If the wars of the last century were fought over oil, the wars of this century will be fought over water." -Ismail Serageldin, The World Bank The giant dams of today are the modern Pyramids, colossally expensive edifices that generate monumental amounts of electricity, irrigated water, and environmental and social disaster. With Deep Water, Jacques Leslie offers a searching account of the current crisis over dams and the world's water. An emerging master of long-form reportage, Leslie makes the crisis vivid through the stories of three distinctive figures: Medha Patkar, an Indian activist who opposes a dam that will displace thousands of people in western India; Thayer Scudder, an American anthropologist who studies the effects of giant dams on the peoples of southern Africa; and Don Blackmore, an Australian water manager who struggles to reverse the effects of drought so as to allow Australia to continue its march to California-like prosperity. Taking the reader to the sites of controversial dams, Leslie shows why dams are at once the hope of developing nations and a blight on their people and landscape. Deep Water is an incisive, beautifully written, and deeply disquieting report on a conflict that threatens to divide the world in the coming years.

Download or read book Large scale dam removal and ecosystem restoration written by Rebecca McCaffery and published by Frontiers Media SA. This book was released on 2024-09-20 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers are vital ecosystems that support aquatic and terrestrial biodiversity and several ecosystem services, including food, water, culture, and recreation. After centuries of building dams on rivers across the world, dam removal projects are now on the rise due to obsolescence, reservoir sedimentation, insufficient return on investment, or river restoration and conservation priorities. Most dam removal projects have focused on smaller structures (< 10 m in structural height), but larger structures have also started to be removed in increasing numbers as practitioners, river managers, conservationists, and the public have gained more experience with the practice. Recent estimates suggest that only a small fraction of dam removals have been scientifically studied, and include mostly small dams and short time scales. Documenting the long-term ecological outcomes of large dam removal (i.e. >10 m tall) represents a new frontier in dam removal research: projects are more recent and provide an opportunity to understand the complex ecological changes that occur with these transformative restoration projects. Here, we aim to collate a diverse array of papers on long-term dam removal research projects involving larger dams (>10 m) to synthesize the issues, outcomes, tools, and experimental designs used to study large dam removal projects from physical, biological, and ecological perspectives. With this collection, we aim to showcase diverse global projects on ecosystem responses to large dam removal; collect perspectives from different disciplines, fields, and geographies; and synthesize the current state of knowledge in this area. We expect that this Research Topic will be informative to ongoing, long-term ecological restoration and monitoring projects related to dam removal as well as to upcoming large dam removal projects. We welcome contributions from all disciplines addressing the physical, ecological, and ecosystem responses to large-scale dam removal. Contributions could include original research in a specific discipline or area, case studies, or synthesis papers that address one or more of these topics in a transdisciplinary approach. Contributors could address any of the following major topics as related to outcomes of large dam removal, alone or in combination: Freshwater, estuarine, and marine aquatic biota; River and reservoir geomorphology; Terrestrial and riparian vegetation; Wildlife; Sedimentation; and Modelling. We would like contributors to highlight key results in their area of study, cross-disciplinary insights, and lessons learned that could inform ongoing monitoring and research efforts in current projects as well as upcoming large dam removals.

Download or read book Big Dams of the New Deal Era written by David P. Billington and published by University of Oklahoma Press. This book was released on 2017-04-20 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: The massive dams of the American West were designed to serve multiple purposes: improving navigation, irrigating crops, storing water, controlling floods, and generating hydroelectricity. Their construction also put thousands of people to work during the Great Depression. Only later did the dams’ baneful effects on river ecologies spark public debate. Big Dams of the New Deal Era tells how major water-storage structures were erected in four western river basins. David P. Billington and Donald C. Jackson reveal how engineering science, regional and national politics, perceived public needs, and a river’s natural features intertwined to create distinctive dams within each region. In particular, the authors describe how two federal agencies, the Army Corps of Engineers and the Bureau of Reclamation, became key players in the creation of these important public works. By illuminating the mathematical analysis that supported large-scale dam construction, the authors also describe how and why engineers in the 1930s most often opted for massive gravity dams, whose design required enormous quantities of concrete or earth-rock fill for stability. Richly illustrated, Big Dams of the New Deal Era offers a compelling account of how major dams in the New Deal era restructured the landscape—both politically and physically—and why American society in the 1930s embraced them wholeheartedly.

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Download or read book Dams and Development written by World Commission on Dams and published by Routledge. This book was released on 2016-05-13 with total page 834 pages. Available in PDF, EPUB and Kindle. Book excerpt: By the year 2000, the world had built more than 45,000 large dams to irrigate crops, generate power, control floods in wet times and store water in dry times. Yet, in the last century, large dams also disrupted the ecology of half the world's rivers, displaced tens of millions of people from their homes and left nations burdened with debt. Their impacts have inevitably generated growing controversy and conflicts. Resolving their role in meeting water and energy needs is vital for the future and illustrates the complex development challenges that face our societies. The Report of the World Commission on Dams: - is the product of an unprecedented global public policy effort to bring governments, the private sector and civil society together in one process - provides the first comprehensive global and independent review of the performance and impacts of dams - presents a new framework for water and energy resources development - develops an agenda of seven strategic priorities with corresponding criteria and guidelines for future decision-making. Challenging our assumptions, the Commission sets before us the hard, rigorous and clear-eyed evidence of exactly why nations decide to build dams and how dams can affect human, plant and animal life, for better or for worse. Dams and Development: A New Framework for Decision-Making is vital reading on the future of dams as well as the changing development context where new voices, choices and options leave little room for a business-as-usual scenario.

Download or read book Riverflow written by Paul Stanton Kibel and published by Cambridge University Press. This book was released on 2022-01-06 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The importance of salmon to the Pacific Northwestâ€"economic, recreational, symbolicâ€"is enormous. Generations ago, salmon were abundant from central California through Idaho, Oregon, and Washington to British Columbia and Alaska. Now they have disappeared from about 40 percent of their historical range. The decline in salmon numbers has been lamented for at least 100 years, but the issue has become more widespread and acute recently. The Endangered Species Act has been invoked, federal laws have been passed, and lawsuits have been filed. More than $1 billion has been spent to improve salmon runsâ€"and still the populations decline. In this new volume a committee with diverse expertise explores the complications and conflicts surrounding the salmon problemâ€"starting with available data on the status of salmon populations and an illustrative case study from Washington state's Willapa Bay. The book offers specific recommendations for salmon rehabilitation that take into account the key role played by genetic variability in salmon survival and the urgent need for habitat protection and management of fishing. The committee presents a comprehensive discussion of the salmon problem, with a wealth of informative graphs and charts and the right amount of historical perspective to clarify today's issues, including: Salmon biology and geographyâ€"their life's journey from fresh waters to the sea and back again to spawn, and their interaction with ecosystems along the way. The impacts of human activitiesâ€"grazing, damming, timber, agriculture, and population and economic growth. Included is a case study of Washington state's Elwha River dam removal project. Values, attitudes, and the conflicting desires for short-term economic gain and long-term environmental health. The committee traces the roots of the salmon problem to the extractive philosophy characterizing management of land and water in the West. The impact of hatcheries, which were introduced to build fish stocks but which have actually harmed the genetic variability that wild stocks need to survive. This book offers something for everyone with an interest in the salmon issueâ€"policymakers and regulators in the United States and Canada; environmental scientists; environmental advocates; natural resource managers; commercial, tribal, and recreational fishers; and concerned residents of the Pacific Northwest.
