Movements against dams not only counts high among all environmental movements in India but also in the world. India’s North East with its increased emphasis on construction of dams has also triggered number of protests in the region. This makes it necessary to delve into the issue of movements against dams in North East India. When the director of Centre for Science and Environment, Sunita Nara...

Dam break analysis plays a very important role in the risk assessment of dams. Large dams pose significantly higher risks to the people and property downstream of the dam as compared to smaller dams. So the flooding risk due to the possible failure of large dams is more crucial. The simulation of exceptional events characterized by high hydraulic and hydro-geologic risk is an actual problem for...

E nvironmentalists often go to great lengths to block the construction of new dams because dams interfere with fish migration, inundate terrestrial habitats, and interrupt natural flows that are necessary for critical ecosystem processes. However, few environmental issues are so simplistically black and white, and dams are no exception. Dams can be an important source of clean energy and for po...

A dam may fail when the loading (overtopping flood, flow through or beneath the dam, earthquake or blasting loading, terrorist attacks, deterioration etc.) exceeds the resistance against overtopping, internal erosion, slope instability, sliding/overturning, excessive deformation etc. To properly describe the causes of dam failures, it is necessary to study characteristics of the dams which have...
