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.

Whether it’s a beaver dam or the Hoover Dam, all dams rely on science to function properly. People first began damming rivers to stop flooding and provide water for irrigation. These early dams were made with simple techniques and technology. Today, dams are constructed to prevent flooding and to provide water for irrigation, hydroelectric power, and freshwater for large populations. Modern advances in dam technology would have never happened if it weren’t for dedicated scientist and engineers. This volume provides an exciting opportunity for readers to learn about fundamental STEM topics. Detailed photographs, diagrams, and fast fact boxes help readers make essential connections to the social studies and science curricula.

Dams have been used to control water for thousands of years, with the oldest known dam being a small earthen structure in present-day Jordan dating to c.4000 BCE. Since then, cultures throughout the world have practised the art of dam-building and the technology has evolved in myriad ways. The papers selected here examine the key technical issues influencing dam construction from ancient times to the early 20th century. In addition they illustrate why various human societies have built dams and how ’social’ (or seemingly ’non-technical’) factors have influenced the process of dam design. Though hydraulic engineering is the primary focus of the book, it also reveals a keen interest in questions of water resources and environmental history.

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.

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.

Rivers are one of nature’s most vital energy sources, and their power can be efficiently harnessed through the construction of dams. But now dams have become a controversial engine in the race toward technological advancement, so much so that the World Commission on Dams convened in 1998 to debate the issue. Are dams a help to society or an agent of environmental destruction? Trevor Turpin explores the answers to that question here in his comprehensive historical chronicle. Among the most amazing feats of human engineering, a dam can sustain societies in a multitude of ways, as 40,000 of them around the world provide such things as electricity, water for farms and cities, and canals for boat navigation. Turpin traces their development, design, and consequences from the Industrial Revolution to now, examining edifices in China, Las Vegas, and places in between. The often contentious debate between environmentalists, architects, and engineers, Dam shows, is a complex one that pits the benefits of dams against the long-term ecological health of nations. Neither a polemic against dams nor a defense of their proliferation, Dam offers a judicious and in-depth account of this cornerstone of our modern age.

CHECK DAM CONSTRUCTION FOR SUSTAINABLE WATERSHED MANAGEMENT AND PLANNING Authoritative and comprehensive reference on the potential for watershed development through the use of check dams Check Dam Construction for Sustainable Watershed Management and Planning summarizes current knowledge of check dams as key soil and water conservation structures in some of the most sensitive and vulnerable ecosystems in the world, as exemplified by the Mediterranean area and the Chinese Loess Plateau, providing detailed information on check dam design and watershed planning, the use of advanced modeling techniques, challenges in dam construction and how to overcome them. The work integrates decades of research in the field of soil and water conservation and gully management, including advanced studies in check dam construction and watershed management. It also covers important new techniques and methods, such as hydrological modeling, isotope tracing, and more. To aid in reader comprehension, the five highly qualified editors have divided the work into three distinct sections. Sections I and II focus on the experience gained from the erosion hotspots in the Chinese Loess Plateau, whereas Section III expands the scope to other regions with different functions for check dams, including headwater ecosystems and alpine environments. Sample topics covered in Check Dam Construction for Sustainable Watershed Management and Planning include: The regulating effect of check dam systems on sediment redistribution and the formation and development of dam systems in small watersheds Water and soil conservation made possible by check dam construction and sediment source analysis of water-sediment retarding effects of check dams The regulation of check dam systems on the erosion dynamic process and the mechanism of erosion reduction by check dams Flood control risk assessment on warping dam systems and the development and utilization model of check dam systems With its systematic coverage of all aspects of dam construction and maintenance, Check Dam Construction for Sustainable Watershed Management and Planning supports decision making by local authorities and can also be used as a professional guide for ecologists, hydrologists, and water resource managers.
