Hai River

The Hai River is a major river system in northern China formed by several tributaries that converge near Tianjin and drain into the Bohai Sea.

Hai River Basin: The drainage area of the Hai River system in northern China. The basin gathers the tributaries that converge to form the Hai River.
Hai River Conservancy Commission: A Chinese water-management agency responsible for the Hai River basin. It coordinates basin-wide water management across multiple tributaries and jurisdictions.
Tianjin: A major port city and municipality in northern China near the Hai River's outlet. The river reaches the Bohai Sea through the urban area of Tianjin.
1939 Tianjin flood: A major flood that inundated Tianjin in 1939 after intense rainfall in the Hai River region. It illustrates the destructive flood risk at the river system's lower end.
Yongding River: A major river in northern China that flows through Beijing and joins the Hai River system. It is one of the principal tributaries feeding the system.
Flood control: Measures designed to reduce the damage caused by overflowing water. Dikes, reservoirs, and channels regulate floods across the Hai's densely settled basin.
Beijing: The capital of China, located in the northern part of the Hai River basin. The city's water demand draws on rivers and reservoirs within the basin.
Hai River flood of 1963: A severe flood in the Hai River basin in 1963 that prompted extensive flood-control works. Its damage drove major changes to reservoirs, dikes, and flood management.
Daqing River: A river in Hebei Province that drains into the Hai River system. Its waters join other tributaries before reaching the Hai.
Urban stormwater management: The planning and infrastructure used to manage rainwater runoff in cities. Rapid urban growth around Tianjin increases runoff entering the lower river.
