Outline of Final Research Achievements

We have developed an index of sediment disaster with disaster occurrence probability, which is the sediment disaster alert system in the present study. The target of the system is surface slope failure taking place with severe rain. The result of the system applied for the case of 2018 severe rain in Kure city, Hiroshima prefecture is shown on the QGIS which is free and open GIS. The GIS shows the probability with color on QGIS. On the other hand, slope failure has been calculated with scalable particle method of numerical simulation, FDPS. We developed scalable simulation system by using SPH method and geotechnic model.

Academic Significance and Societal Importance of the Research Achievements

これまで降雨情報だけを用いて土砂災害の危険度を指標化していたが,本研究により土地の斜度などを含めて確率的に土砂災害の危険度を表示できるようになった.また,従来では実験室規模の斜面崩壊のシミュレーションが行われているものを実スケールでのシミュレーションが可能な仕組みを構築することができた.
