Structural engineering is important in many facets of dam safety. There are a variety of forces against which a dam should be designed to adequately resist including but not limited to: self-weight, static water pressures, wave pressures, sediment buildup pressures, uplift water pressures, wind pressures, thermal loads, ice pressures, and earthquake forces. First and foremost, structural engineers must design the dam to be globally stable (particularly for concrete and masonry type dams; for embankment dams, slope stability is a separate issue). In addition to the global stability of a dam, structural engineers must also design the many appurtenant structures associated with dams to be structurally sound. These structures include spillways, intake towers, outlet conduits, gates, and more. Materials used in the construction of dams include "earth, rock, tailings from mining or milling, concrete, masonry, steel, timber, miscellaneous materials (such as plastic or rubber) and any combination of these materials." [1] Regardless of the material or combination of materials used, dams and their appurtenances must be designed to be structurally stable and meet applicable design criteria.
