Question

Give one advantage of building small check dams to stop the rain water from flowing away.

Answer 1

Check dams are a highly effective practice to reduce flow velocities in channels and waterways. Contrasting big dams, check dams have a faster implementation timeline, are cost effective, and are smaller in scope. Because of this, their implementation will not typically displace people or communities nor will they destroy natural resources if careful design considerations are undertaken..[19] Moreover, the dams themselves are simple to construct and do not rely on advanced technologies – thereby they can be applied in more rural and less advanced communities, as they have been in India’s drylands for some time now.

Answer 2

it can be use for irrigation by small villagers
