Gravity dam

Common card · No. 222813

A 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. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. (In contrast, sections of an arch dam are not independently stable, and instead rely on transmitting force through neighboring sections to the abutments, often anchored into canyon walls.)
