Study of debris flow peak discharge at Kamikamihorizawa Creek

Prediction of the peak discharge debris flow is one most important factors in mitigating disasters. Currently, empirical methods based on relationship between and total volume (magnitude) for many events are used to estimate planning or designing countermeasures Japan. In order with high accuracy, monitoring sensors load cell pressure sensor (hereafter referred as a DFLP system), was installed evaluate various characteristics during floods involving flows at Kamikamihorizawa Creek. During that occurred August 29, 2019 Creek, seven surges corresponding were monitored by system 20-minute period. Based magnitude, observation data Illgraben Schipfenbach has been added previous from literature updated. The magnitude Creek exhibited distributions similar past data, which shows follows trend.
