Outline of Research at the Start

本研究では,洪水・土砂複合災害の結果としての浸水災害を対象にして,地域のリアルタイム浸水予測可能性を論じる.
具体的には,詳細な降雨分布や個別の斜面崩壊場所や河道の横断構造物に依存して浸水が発生する集落の浸水発生の予測可能性を主な研究対象とする.異なる研究分野で開発されたHPCシミュレーションの手法に観測情報を組み合わせて高度化した上で,河床断面形状や横断構造物情報を入力情報として,浸水域と入力情報の関係を得る.その関係を知識として蓄えることでリアルタイム浸水災害発生を予測する可能性を論じる.

Outline of Final Research Achievements

The present study discussed the region's real-time inundation predictability for inundation hazards due to combined flood and sediment disasters. Specifically, we focused on the predictability of flooding in settlements where flooding depends on detailed rainfall distribution and individual slope failure locations, and the HPC simulation methods developed in different research fields were combined with observational information and upgraded. An ensemble of sediment and flood inundation simulations implemented on the supercomputer Fugaku estimated the spatial distribution of damage probability, and we optimized the parameters in the simulations. We compared with the experiments carried out in 2022, which failed to generate any slope failures and, in this respect, could not be adequately compared.

Academic Significance and Societal Importance of the Research Achievements

学術的な意味では,異なる研究分野で開発されたHPCシミュレーションの手法に観測情報を組み合わせて高度化を実施した.スーパーコンピュータ「富岳」上に実装した土砂・洪水氾濫シミュレーションをアンサンブル実行し,被害発生確率の空間分布推定し,シミュレーションにおけるパラメータ最適化を行ったことである.
社会的な意味では,洪水・土砂複合災害の結果としての浸水災害を対象にして,地域のリアルタイム浸水予測可能性を論じた.具体的には,降雨空間的な変動や地形地質の分布によって変化する上流域での斜面崩壊にかかわらず,下流の氾濫域が推定できることを示した.
