Title: Impact Study of Sediment Deposition on Chongqing River Reach after Running the Three Gorges Reservoir
Abstract: After the Three Georges Reservoir running according to 175m scheme,it is showed that the deposits will increase accumulatively with the TGR running in the downtown reach,the river bar will be widen and heighten.At the same time,the movement of bed evolution will be acute.The sediment aggregation will bring out certain negative influence on harbor,navigation,the infrastructures and eco-environment along both banks of the reach of Chongqing.Taking various aspects of research achievements into consideration,the main engineering measurements are put forward in order to decrease the influence,such as reinforcing soil conservation,building reservoirs at upstream to prevent sand sedimentation,narrowing the flow to wash sand,implementing bank regulation,harbor reconstruction and navigable channel treatment etc.These measures will be very effective on decreasing deposition and eliminating the negative effects.
