The gravity dam is a massive concrete or earth type structure. Gravity dams use their own weight to resist opposing forces. They rely on their great weight and size for stability. The gravity dam is the most commonly built dam in the world. typical example of the conventional concrete dam is the Hoover Dam. Changuinola Dam is an example of the RCC arch-gravity dam. A gravity dam requires a large volume of internal fill. An arch-gravity dam can be thinner than the pure gravity dam and requires less internal fill.
