In order to solve the problem, a dam should have a flushing gate to pass the sediment. However, when the flushing gate is not enough large, the intake just upstream of the dam doesn't work due to the sedimentation. In this paper, we study the bed-deformation caused by a dam by using a flume experiment and numerical simulation. In addition, we study the process of flushing sediment from the dam and the bank erosion under the condition that the water level at the dam is decreased with the width of a flushing gate. As a result, it is clarified that the bed topology is governed the water-level at the dam. Moreover, it is possible to simulate the bed-deformation with flushing sediment and bank erosion by employing a model with respective values for angle of repose in water and in air.}, pages = {829--834}, title = {排砂ゲートに制約された河岸侵食を伴う堆積土砂フラッシュに関する研究}, volume = {45}, year = {2001} }
