Kali Hai: Béda antara owahan

'''Kali Hai''' ({{zh-cpl|c=海河|p=''Hǎi Hé''|l=banyu segara}}), sadurungé disebut '''Bai He''' (Chinese: 白河; pinyin: ''Bái Hé''; tegesé "kali putih"; '''Pei Ho''' ing sumber Kulonan), kuwi sawijining [[kali]] ing [[Cina]] kang mili ngliwati [[Beijing]] lan [[Tianjin]] menyang [[Teluk Bohai]] ing [[Segara Kuning]].

Kali He kuwi dumadi saka lima kali kang kagabung ing [[Tianjin]], yakuwi '''Kanal Kidul''', '''Kali Ziya''', '''Kali Daqing''', '''Kali Yongding''', lan '''Kanal Lor'''. Kanal lor lan kidul kakaroné minangka bagéan saka Kanal gedhé utawa ''[[Grand Canal of China|Grand Canal]]''. Kanal kidul gabung karo '''Kali Wei''' ing [[Linqing]]. Kanal Lor gabung karo '''Bai He''' (utawa '''Kali Chaobai''') ing [[Distrik Tongzhou|Tongzhou]]. Kanal Lor (dadi siji karo Bai He) uga dadi siji-sijiné dalan banyu saka segara menyang [[Beijing]]. Mulané, wong "kulonan" (EropahÉropah?) jaman biyèn ngarani kali Hai He minangka Bai He.

At Tianjin, through the [[Grand Canal of China|Grand Canal]], the Hai connects with the [[Yellow River|Yellow]] and [[Yangtze River|Yangtze]] rivers. The Hai He river systems was greatly modified by the Grand Canal. Before the Grand Canal, Wei River, Ziya River, Yongding River and Bai He used to have their own river mouths. When the Grand Canal was built, it cut through the lower reaches of these rivers to collect more water for sailing. Only one water outlet was left, which is the current course of the Hai He.

Hai He is 1,329 [[kilometre|km]] long from the longest tributary. However, from Tianjin to its mouth, Hai He is only around 70km. Its basin has an area of approximately 319,000 [[km²]] (123,000 [[square mile]]s). Its annual flow is only half that of the [[Yellow River]] or one-thirtieth that of the [[Yangtze River]].

Like the Yellow River, the Hai is exceedingly muddy because of the powdery soil through which it flows. The silt carried by the water deposites in the lower reach, sometimes causing water to overflow. The floods from the five major triburaries only has one shallow outlet to the sea, which makes the flood even stronger. Because China's capital and the second largest city Beijing, the third largest city Tianjin are both located in the Hai He Basin, Hai He flood will cause a significant loss. To allevate flooding, reservoirs are built and artificial channels dug to divert floods directly into the sea. For example, the Chaobai river is diverted to the Chaobai Xin river ('Xin' means new) and is no longer joined with the Northern Canal.
