Abstract

 In recent years, the exposure of clay layers has been regarded as a problem in Japanese rivers, and a plan to create a sand bed is being considered. Therefore, it is necessary to elucidate the characteristics of the "mixed layer of clay and sand” formed by bedload. In this study, we focused on the exfoliation of the mixed layer. As a result, the gravel pick-up process on the mixed layer was clarified. Furthermore, it was clarified that the "depth of gravel bite" affects this process. We also considered the relationship between bite depth and adhesive strength.
