What is gravity dam?

Answer 1

A gravity dam is a solid structure, made of concrete or masonry, constructed across a river to

create a reservoir on its upstream. The section of the gravity dam is approximately triangular

in shape, with its apex at its top and maximum width at bottom. The section is so

proportioned that it resists the various forces acting on it by its own weight. Most of the

gravity dams are solid, so that no bending stress is introduced at any point and hence, they are

sometimes known as solid gravity dams

Answer 2

A gravity dam is a type of dam that uses its weight and the force of gravity to resist the pressure of water, holding back the reservoir behind it. Gravity dams are typically made of concrete or masonry and are well-suited for sites with stable foundations and narrow valleys. They are commonly used for water storage, irrigation, and hydroelectric power generation.
