Impact of the Three Gorges Project on the Water Level and Navigation Channel in the Near-dam Reach Downstream

Lu Yongjun ,Chen Zhicong,Zhao lianbai ,Shao Xuejun,Yang Meiqing,Li Yunzhong

Strategic Study of CAE 2002, Volume 4, Issue 10, Pages 67-72

Abstract:

The river channel change, the bed load and bed material armoring, and the water level lowering after the operation of the Gezhouba project are analyzed based on the topographic and hydrologic data. The water level lowering and it's impact on navigation in the period of construction and initial stage operation of the Three Gorges project are predicted by use of the results of mathematical and physical model.
