Knowra Three Gorges Reservoir Three Gorges Reservoir The large reservoir impounded by the Three Gorges Dam on China’s Yangtze River. Its seasonal water-level changes support flood control, hydropower, and navigation.
Three Gorges Dam : A hydroelectric and flood-control dam spanning the Yangtze River in Hubei, China. Its gates and turbines regulate the reservoir’s level and downstream flow.
Three Gorges Dam resettlement : The relocation of more than a million people from areas inundated by the Three Gorges Reservoir. Rising reservoir waters submerged towns and farmland, requiring large-scale relocation.
Yangtze River : The longest river in Asia, flowing from the Tibetan Plateau to the East China Sea. The reservoir occupies a section of the river upstream of the Three Gorges Dam.
Danjiangkou Reservoir : A large reservoir in Hubei and Henan provinces, formed by the Danjiangkou Dam on the Han River. It is another major central-China reservoir, but serves as the source for the South–North Water Transfer Project.
Reservoir operation : The management of stored water releases to meet competing goals such as flood control and power generation. Seasonal operation determines how the reservoir balances flood storage with other uses.
Three Gorges Dam environmental impacts : Ecological and geological changes associated with construction and operation of the Three Gorges Dam. Reservoir filling altered habitats, sediment flows, and conditions on surrounding slopes.
Three Gorges : A series of steep gorges along the Yangtze River in central China. The reservoir inundates the gorge reaches upstream of the dam, transforming their river landscape.
Xiluodu Dam : A large hydroelectric dam on the Jinsha River, an upper reach of the Yangtze. It is a major Yangtze-basin power project upstream, without the Three Gorges Reservoir’s navigation role.
Hydroelectricity : Electricity generated by converting the energy of flowing or falling water. Water released through the dam’s turbines makes the reservoir a major power source.
Landslide : The movement of rock, soil, or debris down a slope under gravity. Water-level fluctuations can destabilize some reservoir-bank slopes and trigger mass movement.
