In the past several years, torrential rainfall has triggered serious slope failures and caused large socio-economic damage due to loss of life and property Japanese nationwide. In recent years, the growing availability of digital topographic data and increased reliability of radar rain gauge data suggest modeling efforts to predict the timing and location of slope failure in mountainous areas in order to reduce risk to human life and property. To address this concern, this paper has tried to reveal a relationship between slope failure ratio and rainfall/topographic factor on Saru river basin using grid based model. Finally we found the followings: 1)slope failure ratio could be estimated using geographic/topographic and radar rain gauge data. 2) The amount of slope failure in the Saru river basin triggered by August 2003 disaster totaled 19 million cubic meters, and 10% of the total amount of sediment produced was flushed out from the river basin as suspended solid.}, pages = {303--308}, title = {レーダー雨量計を用いた崩壊地発生要因の分析と流域生産土砂量の推定について}, volume = {11}, year = {2005}, yomi = {ムラカミ, ヤスヒロ and ナカツガワ, マコト} }
