Sedimentation Development at the End of the Sanmenxia Reservoir and A Proposal for Solving Way

Zeng Qinghua(Department of Sedimentation Engineering,Chinese Institute ofWater Conservancy and Hydroelectric Power Research,Beijing 100044)  
This paper concentrates on the analysis of sedimentation development at the end of the Sanmenxia Reservoir after its completion.The increase of Tongguan Bed Elevation(TBE)has great influence on sedimentation development at the lower reaches of the Weihe River.The maitenance of TBE significantly affects the life and production stabilities in the reservoir region of upstream Tongguan and the industry and agriculture operations in Guanzhong Plain. Based on the sedimentation development law, this paper argues for the necessity of dredging at the reaches between Tongguan and Guduo.
