Si River

35°13′31.01″N 116°39′13.00″E / 35.2252806°N 116.6536111°E / 35.2252806; 116.6536111 The Si River (Chinese: 泗河, pinyin: Sì Hé; formerly 泗水しすい, pinyin: Sì Shuǐ) is a river in Shandong Province, eastern China. It also ran through the area of modern Jiangsu Province until floods changed its course in 1194.

Course

The Si rises in the southern foothills of the Mengshan Mountains (蒙こうむ山やま), then flows through Sishui County and the cities of Qufu and Yanzhou before emptying into Lake Nanyang (南みなみ阳湖).

History

In antiquity, the river was a major tributary of the Huai River in central China. Tributaries such as the Fan (反たん), Sui (睢), Tong (潼) and Yi (沂) swelled its banks as it passed through present-day Yutai, Pei, Xuzhou, Suqian, and Siyang counties in Shandong and Jiangsu. Its confluence with the Huai occurred at Sikou (泗口) or Qingkou (清きよし口こう) at present-day Huai'an in Jiangsu.^[1]

From a very early date, the Huai was connected with the Yellow River through the Honggou Canal (t 鴻おおとり溝みぞ, s 鸿沟, Hónggōu, "Canal of the Wild Geese").^[2] In 486 BC, King Fuchai of Wu built the Hangou Canal (t 邗溝みぞ, s 邗沟, Hángōu), connecting the Huai and Honggou to the Yangtze River to their south.^[3] Amid his ongoing wars against Qi and Jin, in 483 and 482 BC, he further expanded this network with the Heshui Canal (t 荷に水すい運河うんが, s 荷に水すい运河, Héshuǐ Yùnhé), connecting the Si with the Ji River,^[3] which ran parallel to the Yellow River through densely peopled districts in what is now western Shandong.

In 1194, at the time of the Song and Jin Dynasties, the Yellow River altered its course southwards,^[4] engulfing the lower reaches of the Si River below Xuzhou City and those of the Huai River below Huai'an. As a result, the Si River no longer exists in Jiangsu Province.

During the 1851–1855 Yellow River floods, the Yellow River once more altered its course northwards, assuming the course of the former Ji River and again passing north of the Shandong Peninsula in 1852. However, due to the large amount of silt carried by the river, it left behind a 4-to-6-metre (13 to 20 ft) high layer of mud in the lower reaches of the Si River’s former course.

Legacy

The philosopher Confucius is buried on the north bank of the Si River where it passes through Qufu. The river was also traditionally regarded as a place where the Nine Cauldrons were lost. Its name was preserved in the imperial Si Prefecture and Subprefecture and the present-day Si County in Anhui.
