A gravity dam is mostly straight in plan and is known as 'straight gravity dam'. However, it may also be slightly curved in plan. A curved gravity dam resists the external forces by its weight and not by arch action. The most ancient gravity dam on record was built in Egypt more than 400 years B.C. of un-cemented masonry.

Failure of gravity dam occurs due to overturning, sliding, tension and compression. A gravity dam is designed in such a way that it resists all external forces acting on the dam like water pressure, wind pressure, wave pressure, ice pressure, uplift pressure by its own self-weight. Gravity dams are constructed from masonry or concrete.

These gravity dams were part of a water supply system. The Romans built their gravity dams in the Iberian Peninsula region, North Africa and in the Middle East. A dam located at Homs, Syria in 284 A.D. impounded one of the largest reservoirs built by the Romans. The dam was 6,562 feet (2,000 m) in length and held back about 90 million m3 of water.
