The Hai River (Chinese: 海河; pinyin: Hǎi Hé; literally "Sea River"), previously called Bai He (Chinese: 白河; pinyin: Bái Hé; literally "White River"; Pei Ho in Western sources), is a river in the People's Republic of China which flows through Beijing and Tianjin before emptying into the Yellow Sea at the Bohai Gulf.

The Hai River at Tianjin is formed by the confluence of five rivers, the Southern Canal, Ziya River, Daqing River, Yongding River, and the Northern Canal. The southern and northern canals are parts of the Grand Canal. The Southern Canal is joined by the Wei River at Linqing. The Northern Canal joins with the Bai He (or Chaobai River) at Tongzhou. The Northern Canal (sharing a channel with Bai He) is also the only waterway from the sea to Beijing. Therefore, early Westerners also called the Hai He the Bai He.

At Tianjin, through the Grand Canal, the Hai connects with the Yellow and Yangtze rivers. The construction of the Grand Canal greatly altered the rivers of the Hai He basin. Previously, the Wei, Ziya Yongding and Bai Rivers flowed separately to the sea. The Grand Canal cut through the lower reaches of these rivers and fused them into one outlet to the sea, in the form of the current Hai He.

Hai He is 1,329 kilometres (826 mi) long measured from the longest tributary. However, the Hai He is only around 70 kilometres (43 mi) from Tianjin to its estuary. Its basin has an area of approximately 319,000 km2 (123,000 sq mi). Its annual flow is only half that of the Yellow River, or one-thirtieth that of the Yangtze River.


During the Boxer Rebellion, Imperial Chinese forces deployed a weapon called "electric mines" on June 15, at the Baihe river before the Battle of Dagu Forts (1900), to prevent the western Eight-Nation Alliance from sending ships to attack. This was reported by American military intelligence in the United States. War Dept. by the United States. Adjutant-General's Office. Military Information Division.[1][2][3][4]

Like the Yellow River, the Hai is exceedingly muddy because of the powdery soil through which it flows. The silt carried by the water deposits in the lower reaches, sometimes causing flooding. The waters from the five major tributaries only have one shallow outlet to the sea, which makes such floods stronger. Because China's capital (and second largest city), Beijing, and the third largest city, Tianjin, both lie in the Hai He Basin, Hai He floods cause a significant loss. To alleviate flooding, reservoirs have been built and artificial channels dug to divert excess water directly into the sea. For example, the Chaobai river is diverted to the Chaobai Xin river and no longer joins with the Northern Canal.

Due to industrial and urban development in the Hai He Basin, the volume of water flow has greatly decreased. Many smaller tributaries and some of the major tributaries are dry for most of the year. With reduced water flow, water pollution worsens. The water shortage in the Hai He basin is expected to be alleviated by the South-North Water Transfer Project.
