Abstract
Debris flow peak discharge is one of the most important factors when designing control structures. The method to predict the peak discharge, however, has not been established. In this study, field data of debris flow were analized to obtain the method. Through the data processing, it was found that there is a good corelation between peak discharge and magnitude (total volume of debris flow). As the total volume of debris flow can be predicted to some extent based on the volume of sediment available upstream or the volume of supplied water calculated from amount of rainfall, the peak discharge can be predicted by the empirical equations proposed.
