Question

"Building crescent shaped earthen embankment in level terrain is better
than the construction of large dams across the river to store water
Analyse this statement with their effects.​

Answer 1

Answer:

An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil, sand, clay, or rock. It has a semi-previous waterproof natural covering for its surface and a dense, impervious core. This makes such a dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance.

Answer 2

Answer:

The final answer to the question is:

Building crescent shaped earthen embankment in level terrain is better than the construction of large dams across the river to store water because crescent shaped earthen embankment is more economical , takes less area and can be installed at distant places.

Explanation:

Building crescent shaped earthen embankment in level terrain is better than the construction of large dams across the river to store water because of the following factors:

• making of earthen embankment is cheaper in comparison of dams which take a huge area when the sole purpose is to store water.
• crescent shaped earthen embankments can store enough water to  irrigate lands and refill wells.
• it can easily be made waterproof by using plastic, gravels, sand and mud.
• it doesn't require huge areas in comparison to the reservoirs of dams.
• it can be constructed far away from rivers but dams can only help to irrigate places close to river.
