[0002] A dam is a water conservancy project that stores and regulates water by intercepting rivers or streams, usually constructed from materials such as concrete, soil, and rock. Its core functions include flood control (by regulating flood flow), water supply (storing water resources for agricultural irrigation and urban water use), power generation (converting water energy into electricity), and improving navigation (stabilizing downstream water levels). According to structural types, dams can be divided into gravity dams (relying on their own weight to resist water pressure), arch dams (using arch structures to transfer water pressure to both sides of the mountain), and earth-rock dams (constructed from earth and rock materials). Modern dams are often equipped with spillways, gates, drainage systems, and other facilities to ensure safe operation, such as the Three Gorges Dam, which not only has the world's largest hydropower station, but also balances flood control and power generation needs through multi-layered flood discharge design.
