Q1: What is a gravity dam?

A gravity dam is a type of dam structure that is primarily designed to resist the force of gravity and hold back water or other materials. It relies on its own weight and mass to counteract the horizontal pressure exerted by the water or other materials it is retaining. Gravity dams are among the oldest and most common types of dams used for various purposes, including water supply, irrigation, flood control, and hydroelectric power generation.
