Water Resources Class 10 Notes Geography: Chapter 3

What are Water Resources?

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.

1. Groundwater: Water which is obtained from a depth of more than 15 meters is known as groundwater. 4. Water Scarcity: Shortage of water as compared to its demand is known as water scarcity.
2. Hydroelectricity: The power which is generated with the help of running water is called hydroelectricity. 5. Rainwater Harvesting: The technique of increasing the reserves of groundwater by capturing and storing rainwater and by constructing structures such as percolating pits, check dams, etc., is called rainwater harvesting.
3. Soil: The upper layer of the ground containing weathered rocks and humus is called soil.
