Gorge Dam

A gorge dam is a type of concrete dam, typically characterized by its thin arch or gravity arch design, constructed within a narrow, steep-walled gorge or canyon. The natural topography of the gorge is crucial to the dam's structural integrity and stability. The steep sides of the gorge provide significant abutment support, allowing the dam to transfer the immense water pressure to the rock walls. This design minimizes the required volume of concrete compared to other types of dams, making it a cost-effective solution for suitable locations. Gorge dams are typically used for hydroelectric power generation, water supply, and flood control. Key design considerations include the geological stability of the gorge walls, potential for seismic activity, and the hydrological characteristics of the river or stream.
