Dams and Reservoirs

India is a country of rivers where the construction of dams and reservoirs is inevitable. Dams serve several important purposes, such as hydroelectric power generation, supply of water for irrigation, flood management and providing water for households and industries. Rivers and dams on them are extremely important in strengthening the economy and ensuring protection from natural disasters such as floods. They play a vital role in India’s economic progress and public welfare.

When preparing for Defence exams like NDA, CDS, AFCAT, Army Agniveer, SSB Recruitment, and CRPF, candidates will thoroughly research this topic online.

Why are Dams Built?

India is called the country of rivers, and many dams have been constructed here. Dams are constructed to fulfill various purposes. These mainly include providing water for irrigation, protecting from the effects of floods, increasing power generation, and ensuring water supply in water-scarce areas. These are the main reasons for the construction of dams, which play an important role in the economic and social progress of the country.

  • Irrigation: One of the main reasons for building a dam is irrigation, using the water of which the farmer increases the yield of his crops.
  • Electricity generation: Electricity can be produced using a dam, which is generated by using hydroelectric energy, which is a clean and renewable energy source.
  • Flood control: There are many places in India where excessive water increases the possibility of floods, so dams are constructed to stop the excess flood water.
  • Water supply: The water of dams is also used at the place where there is a problem of drinking water. Therefore, the dam provides its water for drinking water supply, industrial use and domestic use.
  • Fisheries: The water of dams is also used in fisheries, in which the construction of reservoirs encourages fishermen, which also benefits the local economy.
  • Tourism: By developing tourist places around the dams, tourists can be attracted and by establishing a dam, the economic condition of a new place or region can be improved.

Difference Between Dams and Reservoirs

A dam is a barrier to the flow of a river. It could be a stone wall, or a concrete wall across the river to stop the flow. This is called Dam. A reservoir may be a clay or rock deposit. These dams are well-designed and constructed to completely stop the flowing water. Appropriate drainage channels have been installed on top of the dam so that flood water can safely flow downstream.

A reservoir is a part where water is stored behind a dam. They are designed to accumulate to keep all the water flowing throughout the year, given the storage capacity of the valley behind the dam. The Reservoir is designed to accommodate the expected sludge from the inlet.

A dam and a reservoir are both often designed for a life of 100 years.
