TL;DR: In this article, the authors used a multi-phase flow model to examine the impulsive waves generated by collapse of steep slopes at a water body and investigated the possible effects of slope erodibility on the motion of the landslide and the resulting waves by comparing a sub-aerial landslide on a rigid slope to that on an erodible slope.
