Book excerpt: Dams & river regulation have become an integral part of 20th-century landscape & livelihood. Virtually every river in the lower 48 states is now regulated by dams, locks, or diversions. This report illustrates the downstream consequences of dams & explains the basis on which rivers can be scientifically managed. Following a look at a free-flowing river -- the upper Salt River of Arizona -- & its natural cycles of flow & sediment, 6 regulated rivers are examined. Each of these rivers -- the Snake, Rio Grande, Chattahoochee, Platte, Green & Colorado -- highlights a particular use of a dam or a particular downstream effect.

Book excerpt: Dams profoundly impact the geomorphology of rivers by altering the natural patterns of water, sediment and energy flow in rivers. These changes have a largely negative impact on aquatic and riparian ecosystems upstream and downstream of the dam. Natural dams also impact river geomorphology, although with positive and negative repercussions for aquatic and riparian organisms. In 2002, the 33rd Binghamton Geomorphology Symposium convened under the theme "Dams and Morphology," and featured invited papers and contributed posters on topics of natural dams, artificial dams, and dam removal. Fourteen of these papers have been included in this volume.

Available in PDF, EPUB and Kindle. Book excerpt: Scientific Essay from the year 2013 in the subject Environmental Sciences, grade: 10.0, Indian Institute of Technology, Delhi, language: English, abstract: According to WWF: • Worldwide the total amount of water stored in dams is 3-6 times more than that contained in rivers. • The wetlands area during the 20th century has decreased by over 50%. • Out of the 10,000 recorded freshwater species more than 20% have either become extinct, threatened or endangered in recent times. These facts are enough to justify the tremendous impact on environment dams are having. Large scale projects like dams are often floated as important and necessary means of economic development. But this development comes at some or the other cost. Cost to the environment, development and society. So what are dams really for? • Water supply for the general public for domestic uses as well as irrigation which is imperative for our agrarian Indian society. • Hydroelectric power generation. India is the 7th largest producer of hydroelectric power with 114 Tetra-watt hours. It produces 3.3% of the world total. • Dams impede the turbulent and sudden flow of water to prevent floods. Well that is what they are for and granted many of them achieve the above given purposes but they are subject to widespread criticism and debate. Several vehement national and international movements have brought into light the severe problems associated with them. Dams have been criticized for disturbing natural water flows, affecting deposits of nutrients as well as lifecycles of species that depend on freshwater habitat. Reductions in water quantities can increase salinity and make the water unusable for drinking and irrigation. The transport of sediments that are crucial for natural cycles is also affected. This may cause flood risks, lower groundwater tables and in turn affect entire ecosystems. With that said we must point out that dams do not always have a negative impact on habitats. E.g. once reservoirs become established they can become sites where birds can thrive. There are cases where dam projects have taken up significant compensation for the environmental damage they had caused during their initial phases, but these cases are few and far between. In this report, we take up the issue of impact of dams from three different perspectives which we believe are best suited for such a topic: - Economics, Population and Risks and Hazards. We first present them individually and give a brief analysis of each perspective then we present a comprehensive and thorough conclusion at the end.

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the various factors affecting fluvial systems, the processes governing them, system responses arising from human-nature interventions, and geospatial and geo-ecological modeling to understand system behaviour better and restore degraded ecosystems around the globe. Thanks to their hydrological and agro-ecological advantages, humans have settled along riverbanks since the dawn of civilization. Thus, the ancient "ecumene" (settlements) were located near major rivers worldwide. This legacy of river-based civilizations continues to this day in many forms. However, in the course of the 'Anthropocene' era, countless fluvial systems have been altered by human interventions in the form of large-scale dams and barrages, changes in land use and land cover, road-stream crossings, mining of sand and gravel, mushrooming of brickfield, expansion of modern agriculture, industrial growth, and urbanization. Thus, the present-day development pattern threatens fluvial systems, especially riverine morphology and ecosystems. In brief, human-induced morphological changes, water pollution, eutrophication, and related damages to aquatic organisms are the major threats to fluvial systems. Thus, maintaining the 'environmental flow' of the world's major rivers to preserve the proper functioning of riverine ecosystems and promote sustainable development is a global challenge.
