The Hai He ( Chinese  海河 , Pinyin Hǎi Hé  - "Sea River"), formerly also called Bai He ( Chinese  白河 , Pinyin Bái Hé , W.-G. Pei Ho  - "White River"), is a Chinese river that runs through Tianjin flows and flows into the Gulf of Bohai in the Yellow Sea .

From Tianjin, the Hai He is connected to the Huang He ("Yellow River") and the Yangtze via the Imperial Canal . The Hai He river system was fundamentally changed by this channel. Before that, the Wei He , the Ziya He , the Yongding He and the Bai He each had their own estuaries ; However, since the water of these rivers was needed to guarantee the navigability of the Kaiserkanal, only one of the river underflows remained. This corresponds to the current course of Hai He.

The Hai He arises in and around Tianjin through the confluence of the southern Imperial Canal , the Ziya He, the Daqing He , the Yongding He and the northern Imperial Canal . The southern Imperial Canal is also fed by Wei He at Linqing . The northern Imperial Canal corresponds to the course of the Bai He ( Chaobai He ) from the Beijing district of Tongzhou . Since this was Beijing's only access to the sea, the Hai He was also referred to as Bai He by Europeans and Americans.

The Hai He in the narrower sense is only 70 km long on the route from Tianjin to its mouth. However, if you add its longest tributary, the result is a length of 1,329 km. Its catchment area is approximately 319,000 km².

Historical events
