Abstract

 Large-scale bank erosion caused by channel change during flood often causes serious disasters in gravel bed rivers. In this study, we focused on the influence of sediment dynamics in river channel on the channel change inducing bank erosion. From the results of sediment balance in the Pekerebetsu River and the Otofuke River during a flood, we showed the possibility that sediment supply from the bank affect stream channel change to expand bank erosion in the river. We carried out the experiments on the influence of sediment supply from the bank on the channel change, and showed that sediment supply from the bank can be a cause of channel change inducing large-scale bank erosion.
