EROSION OF CLAY BED CAUSED BY THE ACTION OF BEDLOAD AND MIXED-LAYER FORMATION

Abstract

 In the actual river, the shale bed with consolidated clay is exposed and eroded, which causes problems inriver management. There are few studies on clay bed, and the change process of clay bed has not been clarified. In this study, we aimed to clarify the deformation process of clay bed based on the experiment was conductedusing the straight channel and the curved channel. Previous studies have revealed that when bed load is transported to the clay bed, a mixed layer is formed. However, there are many unclear points about the formation process of the mixed layer. Therefore, we focused on the formation process of the mixed layer.
