WebNov 14, 2024 · Gravity dams are triangular-shaped made up of masonry. Generally, four different kinds of gravity dams are found, such as straight, curved, hollow, and solid gravity dams. Moreover, these are of massive size for retaining a large quantity of water. The Grand Coulee Dam (USA) is an example of a gravity dam. Buttress Dams WebA gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section.
