Question

Give reason why the base of the reservoir and dams are broader

Answer 1

Dams have Broader Base. ... Thus, as the depth increases, more and more pressure is exerted by water on the wall of the dam. A thicker wall is required to withstand greater pressure, therefore, the thickness of the dam increases towards the bottom

Answer 2

Answer:

The reason is that the pressure exerted by a liquid increases with its depth. Thus, as the depth increases, more and more pressure is exerted by water on the wall of the dam. A thicker wall is required to withstand greater pressure, therefore, the thickness of the dam increases towards the bottom.

hope this helps
