Selection of reservoir site

SELECTION OF RESERVOIR SITE Before finally selecting the reservoir site following factors should be seriously considered. Catchment area should have such geological conditions that percolation and absorption losses are minimum. Available run-off should be maximum. The site should be free from fissured rocks. This will avoid possibilities of leakage when reservoir is full to capacity. The reservoir site must have adequate capacity. The reservoir basin should have a deep narrow opening in the valley so that the length of the dam may be kept minimum. Heavily silt laden tributaries should not lead their discharge to the reservoir. Suitable site for dam should be available. It will be an ideal site if dam is constructed atthe narrow and shallow part of the river which lies down stream of the deep river. It is very important point as cost of dam is often a controlling factor in selection of the reservoirs site.…
