Web8 de may. de 2024 · For simulation of the erosion and deposition processes in the Pekerebetsu River, a numerical model iRIC Nays2DH (iRIC Project 2010) was applied, which calculates horizontal two-dimensional (2D) flow, sediment transport, and changes to river-bed and river-bank morphology. Geology and geomorphology of western Tokachi Web10 de sept. de 2024 · Abstract. The prediction of debris flows is relevant because this type of natural hazard can pose a threat to humans and infrastructure. Debris-flow (and landslide) early warning systems often rely on rainfall intensity–duration (ID) thresholds. Multiple competing methods exist for the determination of such ID thresholds but have …
