摘要：
Heavy rains brought about by Typhoon No. 7 and the Baiu front from July 3 to July 8, 2018 caused severe damage to the surrounding areas, including Western Japan. Significant damage predominantly occurred in Hiroshima, Okayama, and Ehime Prefectures from July 6 to July 8. In this torrential rainfall event, the damage was enhanced by the simultaneous occurrence of various disasters, including debris flows, slope failures, erosion and depression, flooding, driftwood, and inside water inundation, caused by the extreme volume of rainfall. In this study, outlines of these geo-disasters in Hiroshima Prefecture and some of their characteristics are given, and suggestions for future disaster prevention and mitigation are discussed.
