Research Of Sediment Problem And Treament Scheme About Yellow River Water-diversion Project For Weishan Irrigation Area

Weishan Irrigation area is one of the largest six Yellow River Water-diverson irrigation projects in China.It supplys 65 percent of the water used for agricuitural irrigation, industry and water city building in Liaocheng Distric.At same time,it supplys water for Tianjin city and Hebei province. It plays important role in promoting the region economic development. However, it also diverses large quantity sediment with water diverson, because Yellow River is a famous heavily slit-carrying river in the world. Desilting sediment has produced 1,533hm2 highland beside the sand channel and sand transport cannal. This has produced many problems such as region environmental deterioration, productivity level down and social contradiction sharpened and so on. This also directly impacts on water-diverson the mission of carrying out smoothly, and Weishan Irrigation area continual development.This paper have studied heavy sand pool using scheme mainly through sand containt in water flow of the Yellow River, situation analysis, and according to all the main control irrigation in irrigation area in diverted water volume, water diversion area and calculated the time each case led sediment, through investigation, to determine the scope of the investigation position, sank, meet the irrigation area and water engineering mud treatment needs. For settling basin area are system planning research.Sediment management measures research include: highland villages governance research foundation facilities construction move and research west sand transport canal reconstruction project construction research things settling basin connected canal construction engineering research settling basin expansion research.
