[HTML][HTML] Investigating the release and flow of snow avalanches at the slope-scale using a unified model based on the material point method
Snow slab avalanches start with a failure in a weak snow layer buried below a cohesive
snow slab. After failure, the very porous character of the weak layer leads to its volumetric …
