Why the dams are made broader at base than the top??

pls answer in easy language
Question asked by: vinayreem1

Asked on: 07 Jun 2010

The dam needs to be very stable of course, and having a broader base helps give the dam the stability necessary to stay in place.

Secondly, the further down in water you go, the stronger the pressure from the water that is exerted, and therefore having a broader base helps to deal with the increased pressure that comes at an increased depth.
