Question

how the following activities affect the conservation of water a) CONSTRUCTION OF CHECK DAMS , B)Concreting of courtyards

Answer 1

construction of dams

Answer 2

Construction of check dams (positively) and concreting of courtyards (negatively) affect the water conversations

Explanation:

• A check dam is a small, temporary, dam built across a drainage ditch, waterway, and swale to impede erosion by decreasing the velocity of water flow. Check dams are used primarily to conserve soil, improve land, and control water velocity.  As a vital measure water and soil conservation a measure was check dams that have been built on a huge scale. The building of check dam has led to rise in the level of groundwater
• Concrete courtyards have left very little open grounds thereby not allowing water to soak resulting in decrease in the level of groundwater. To counter this artificial recharging of ground through the technique of rainwater harvesting is very essential.
