Its reservoir submerged a large area of land, forcing over a million people to relocate. "Dam related relocation affects society in three ways: an economic disaster, human trauma, and social catastrophe", states Dr. Michael Cernea of the World Bank and Dr. Thayer Scudder, a professor at the California Institute of Technology.

Some effects of dam removal include erosion of sediment in the reservoir, increased sediment supply downstream, increased river width and braiding, re-establishment of natural water temperatures and recolonisation of habitats that were previously unavailable due to dams. [95] The world's largest dam removal occurred on the Elwha river in the U ...
The reservoir emptying through the failed Teton Dam on June 5, 1976 Ruins of the dam of Vega de Tera (Spain) after breaking in 1959. A dam failure or dam burst is a catastrophic type of structural failure characterized by the sudden, rapid, and uncontrolled release of impounded water or the likelihood of such an uncontrolled release.

It started with a bang at 3 a.m. Monday as the residents of Derna were sleeping. One dam burst, then a second, sending a huge wave of water gushing down through the mountains towards the coastal ...
There are several ways dams can be removed and the chosen method will depend on many factors. The size and type of the dam, the amount of sediment behind the dam, the aquatic environment below the dam, who owns the dam and what their priorities are, and the timeframe of dam removal are all factors that affect how the dam will be removed.

The Hoover Dam. In the past, large dams have often been the focus of water storage efforts. Many large dams and their reservoirs have brought significant social and economic benefits. For example, Egypt's Aswan High Dam, built in the 1960s, has protected the nation from drought and floods and supplies water used to irrigate some 15 million ...
The following table lists the largest man-made dams by volume of fill/structure. By general definition, a dam is a barrier that impounds water or underground streams, hence tailings dams are relegated to a separate list.
These factors have destroyed much of the reforestation. The study predicted that, should the degradation continue at the same rate, the green dam project will disappear during the next few decades, in the analyzed region. For effective control of LDD in Algeria, the study concluded that, in order to move the project forward successfully:
