Due to the heavy rain of July in 2018, several levees of the Oda River and its tributaries in the Mabi district of Kurashiki City were breached and serious inundation disaster occurred there. In this area, most causes of the levee breach were due to the overflow, but there were some places where the levees did not break despite the overflow. Since most of the causes of levee breach in Japan are due to overflow, it is very important to predict the bank break due to overflow. In this study, physical quantities that affect the levee breach were selected and examined whether or not the levee breach could be predicted using flood analysis. As a result, it was clarified that the time averaged water level difference between the river side and residence side before the levee broke could be an important index for predicting the levee breach due to overflow.
