| Abstract: | From Jun.2003 to Sep.2006,the Three Ggorges Reservoir is running with the 135-139 m dispatching operation scheme.The scheme means the water level is 139m during low water season and 135m during flood season.The backwater end is located at Lidu in Fuling district,and the reach ever in back water is below Fengdu.Through analyzing the prototype observation data of the Three Gorges Reservoir,the variety characteristics and the gradation of sediment in this reach has been studied.The rule of sediment motion is obtained based on the analysis of sediment size in this reach,which could be a preliminary understanding of sediment motion rule in the Three Gorges Reservoir district. |
