It is important to make small check dams across the flooded gullies because they
(i) Hold water for irrigation
(ii) Hold water and prevent soil erosion
(iii) Recharge ground water
(iv) Hold water permanently

  1. (i) and (iv)

  2. (ii) and (iii)

  3. (iii) and (iv)

  4. (ii) and (iv)

  5. (i), (ii) and (iii)


Correct Option: E
Explanation:

A major portion of water stored behind dams in the world is withdrawn for irrigation that is, evaporation and transpiration needs. Water used in excess of evaporation and transpiration needs appears in the system as surface or groundwater. The total quantum of flow and size and frequency of peak floods in the flood season reduce in the downstream due to a dam, reducing flood hazard due to inundation of land, crop and property. It also reduces congestion of run off in plains and coastal lands. Any soil erosion such as gullies already formed can be tackled by the construction of dams or obstructions. 

Therefore, the correct answer is option E.

The drawback of dam is

  1. Block fish migration

  2. Can cause flood on dam side area

  3. Displace local people

  4. All of the above
