Question

"It is important to make small check dams across the flooded gullies". Which of the given reasons is correct?

(ii) Prevent soil erosion
(iii) Recharge groundwater
(iv) Hold water permanently

• A. (i) and (iv) are correct
• B. (ii) and (iii) are correct
• C. (iii) and (iv) are correct
• D. (ii) and (iv) are correct
• E. (i), (ii) and (iii) are correct

Answer 1

Answer: (E)

(i), (ii) and (iii) are correct

• The “check dams” built across seasonally flooded gullies are used for irrigation and simultaneously check soil erosion.
• However, the main purpose is to recharge the groundwater beneath which spreads out to recharge wells.

Thus, the statements (i), (ii), and (iii) are correct. So, the correct option is E.
