It is important to establish a practical method for estimating sediment discharge hydrograph in rivers with a large amount of sediment yield during floods. In this study, we develop the practical method for estimating sediment discharge hydrograph by calculating flood flow and bed variation analysis in stages so as to bring the observed and calculated bed aggradation and channel migration closer to agreement. The present method was applied to 1995 flood of the Hime River. As a result, it shows that the present method could estimate sediment discharge hydrograph in rivers with a large amount of sediment yield during floods.
