Depth-averaged mixture model for development processes of debris flows over a steep unsaturated mobile bed

S Takayama, R Karasawa, F Imaizumi - Landslides, 2024 - Springer
As water flow erodes bed sediment in a steep channel, a partly saturated debris flow, which
has an unsaturated layer in its upper part, develops while interacting with a subsurface flow …

Assessing the impact of sediment characteristics on vegetation recovery in debris flow fans: A case study of the Ohya Region, Japan

S Yousefi, F Imaizumi - Ecological Engineering, 2024 - Elsevier
