Question

State five advantages of a check dam.

Answer 1

Five advantages of a check dam are:

1. Reduces soil erosion by slowing the water flow and allowing sand to settle.
2. Groundwater is recharged by increasing water infiltration into the ground.
3. Increases agricultural output by supplying more water for irrigation.
4. Controls excess drainage after heavy rains, preventing floods.
5. Improves local ecosystems by constructing small water reservoirs that support plant and animal life.
