Shuhe River is located in the south of Shandong Province and the north of Jiangsu Province in China. Originated in the southern foot of Yishan, Yishui County, Yimeng Mountain Area, Shandong Province. It flows south parallel to Yishui, passes through Tancheng County and enters Jiangsu Province. It was originally merged into Surabaya in Suqian City and then merged into Huaihe River. 1 128 ~ 1855, the south of the Yellow River moved into the sea from Sishui under Xuzhou City and the main stream of Huaihe River under Huaiyin City. Later, due to the high siltation of the riverbed, the Yellow River moved northward at 1855, leaving the abandoned old course of the Yellow River, and the Shuhe River lost its channel into the Huai River.
The basic flow direction of Shuhe River in Juxian County is north-south, but after flowing out of Juxian County, the river section passing through Linyi and only lanshan district City gradually turns east-west. In fact, it generally runs north and south, and finally enters Jiangsu from Tancheng, Linyi, and finally merges into the Yellow Sea.
