Qu river is located in the east of the Yellow River, west of Lvliangshan, is a tributary of the Yellow River. The river a total length of 74.9 km, originated in the eastern floor of Stone House, flowing through the Central Plains, Liulin counties into the Yellow River. Basin area of 1220 square kilometers, of which: Shilou County, 848 square kilometers, accounting for 70% of the basin, is Shilou County’s main economic zone. About 90% of the area of the Quchushan River Basin belongs to the loess hilly and gully area, and soil erosion is very serious. It is an important river from which the Yellow River sediment comes from. According to Pei River Hydrological Station observation, annual average annual runoff of 51,500,000 cubic meters, water flow 0.342 cubic meters per second, the maximum flood 3380 cubic meters per second, annual sediment transport 15.3 million cubic meters per square kilometer of soil erosion modulus 12,500 tons.
