Liu -Yang: Riverbed adjustment response of Jingjiang Reach under the change of flow and sediment -911 -APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH 15(3): 911-922. Abstract. According to the hydrological and sediment data before and after the impoundment in the Three Gorges Reservoir and the measured topographic data of Jingjiang Reach, the article analyzes the response mechanism of erosion and deposition of riverbed in Jingjiang Reach for flow changes, suspended sediment recovery and bed

The main conclusions are as follows: After the impoundment of Three Georges Reservoir, the low flow has increasing and streamwise recovery of suspended load strengthen the scouring ability of the overall Jingjiang Reach. After the impoundment of Three Georges Reservoir, the Jingjiang Reach shows conforming and cumulative erosion; the low flow channel is the principal part of riverbed scouring.
