Multipurpose river projectsc
- Dams are being constructed in India for irrigation, electricity generation, flood control, recreation, inland navigation and fish breeding. For example : In Satluj-Beas River Basin, the Bhakra Nangal project is used for hydel power generation and irrigation.
- The construction of these dams has come under a lot of scrutiny as it affects the natural flow of river water.
- It has also been the cause of many social movements like Narmada Bachao Andolan, Tehri Dam Andolan, etc. As construction of dams causes displacement of local people.
- It has several ecological consequences like salinisation and has also widened the gap between the rich and the poor.
- These dams were constructed to check floods, but ironically they increased their frequency due to sedimentation in the reservoirs.
