内容記述
Heavy rainfall was observed in Hiroshima Prefecture in June 2016 and caused sediment disasters at many locations in the east part of Hiroshima Prefecture. We have analyzed the sediment disasters using two kinds of sediment disaster warning models. The models use the short-term rainfall index and long-term rainfall index to demarcate the threshold for sediment disasters (critical line:CL).As a result, we found that that effectiveness of the warning models can be improved by using precipitation probability statistic data to demarcate the CL in case of above sediment disasters.
