Question

why the base of the dam is made broad​

Answer 1

Answer:

Dams are built broad at the base . This is done so that the Dams can withstand the high pressure that is exerted by flowing water . As the pressure of the water increases when the depth of water increases . Hence , the broader base helps the dams to withstand the increased pressure of water .

Answer 2

Answer:

Here is your 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 damincreases towards the bottom.
