Vedclass · Answer

(D) Small check dams are constructed across flooded gullies to manage water resources effectively.$(i)$ While they may provide some water for irrigation,it is not their primary purpose.$(ii)$ They hold water for a short period,which helps in reducing the flow velocity of water,thereby preventing soil erosion.$(iii)$ By holding water,they allow it to percolate into the soil,which helps in recharging the groundwater levels.$(iv)$ They do not hold water permanently; they are designed to hold water temporarily to facilitate infiltration.Therefore,statements $(ii)$ and $(iii)$ are correct.

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
