抄録

In September 2011, the largest discharge in recorded history was observed in Otofuke River, causing riverbank erosion in various parts of the basin. Damage was especially serious in the middle reaches, where part of a dike was completely washed out. The results of a survey suggested that the cause of the dike breakage was bank erosion associated with the development of a meandering channel. As the related development mechanism and predominant factors have not yet been clarified, this remains a priority for disaster prevention. In this study, the meandering-channel development process was reproduced using a slope failure model that linked bank erosion with bed fluctuations. The study attempted to clarify the meander development mechanism and predominant related factors based on this model.
