- TEMPORAL VARIATIONS OF FREQUENCY OF TORRENTIAL RAIN AND RELATIONSHIP OF HUMAN DAMAGE AND PRECIPITATION IN PAST FLOOD AND SEDIMENT-RELATED DISASTERS
抄録
In order to analyze regional changes frequency of torrential rain that defined hourly precipitation of 50 mm, 75 mm and 100 mm, we represented the spatial distributions of frequency of torrential rain. Secondly, we analyzed relationship of human damage and precipitation pattern in past flood and sediment-related disasters. Number of candidate disaster which more than five persons are killed or went missing in is 49 since 1976. We used total precipitation, total precipitation and maximum hourly precipitation during a disaster period as indicators of precipitation pattern.The results of the present research are summarized as follows:(1)From the 1980-1989 decade to the 2000-2009 decade, frequency of torrential rain had increased in Shikoku area, Kyushu area, Tohoku area and Hokuriku area. In particular, in Tohoku and Hokuriku area, torrential rain did not occur about 30 years ago, but in resent years, torrential rain occurs (2)Relationship of human damage and precipitation are studied by means of the statistical hypothesis test. The results show that Kyushu area has a higher resistibility for disasters than Setouchi area.
