After wildfire events, water repellent soil is often found in the subsurface layer of channel bed burnt area. Debris flows generated from basins and ensuing entrainment pose imminent threat to infrastructure human lives. However, fundamental interaction mechanisms debris flow overriding resulting impact force on debris-resisting barriers have yet be elucidated. In this study, physical flume exp...

Runoff-generated debris flows are a common post-fire hazard in the western United States and growing number of regions around world. As wildfire continues to emerge across broader range geographic plant communities, there is an increasing need for generalizable methods predict debris-flow initiation. The prediction flow during intense rainstorms has traditionally relied upon empirical rainfall ...

Submarine debris flows and their generated waves are common disasters in Nature that may destroy offshore infrastructure cause fatalities. As the propagation of submarine is complex, involving granular material sliding wave generation, it difficult to simulate process using conventional numerical models. In this study, a model based on smoothed particle hydrodynamics (SPH) algorithm proposed fl...
