Abstract: This paper revises current understanding of the flow at the base of a headcut and suggests a new model which employs the concept of a vortex flow. A distinctive feature of the vortex flow is the presence of the upstream-directed ...

Abstract: The stopping process of debris-flow pulses is a complex phenomenon that expresses both the characteristics of a non-Newtonian fluid when it flows and those of a soil when it comes to a stop. In order to capture this ...
