| Outline of Final Research Achievements |
Local heavy rain caused a serious debris flow disaster with 75 victims, and destroyed many buildings on Hiroshima City on August, 20, 2014. The accumulated rainfall amount from 1:30 am to 4:30 am was recorded at over 200 millimeters. Usually, local heavy rain is observed by AMeDAS, and by C-band radar operated by MLIT of Japan for disaster prevention in Japan, which have spatial resolutions of 2.5 km and 1 km, respectively. The X-band MP radar system is the new radar system, and rainfall observations by the X-band MP radar system are more detailed than by the C-band radar. X-band MP radar can observe local rainfall almost in real time throughout the entire territory of Japan, to support appropriate disaster prevention activity, and the minimum observation area is in a 250 meter mesh. The accumulated rainfall monitoring system is crucial for disaster prevention. Those hazard levels of the accumulated rainfall amount are quite important to estimate occurrences of disasters.

| Academic Significance and Societal Importance of the Research Achievements |
今回のＸバンドＭＰレーダの利用については、国土交通省のWEBサイトXRAINの例のように即時性（１分間降雨量データ）を目的とする場合は良いが、これでは蓄積雨量情報が分からず、気象庁が設定している、１時間蓄積雨量警報レベルが全く利用できない状況となっている。自治体の防災担当者は、１分間降雨量データのみならず、蓄積雨量情報も住民の避難警報・警告の重要な根拠としているため、本研究はきわめて重要な情報を提供できるものと考えられる。
