Abstract: Boundary layers will separate along a curved dike causing circulating flow which affect the overall flow field and increase sedimentation. Separation and increased sedimentation are common phenomena in the projects of water conservancy, sea-route and power station. We experimented in a50cm-width flume with a dike which had been placed as a barrier, adopting the method of sucking-spouting water. It could improve the flow pattern; reduce the size of circulating flow and the sedimentation volume downstream of the dike. Based on the experimental data, we had the relation between the size of circulating region and the sucking-spouting discharge, and the relation between the sediment volume and the sucking-spouting discharge. These results have important science meaning and utility value.
