Research on formation conditions of V-shaped debris flow with impact and deposit;

The authors discuss roundly source of loose earth for impact deposit debris flow to develop taking pingchuan debris flow,one of the quite typical impact deposit debris flows in southwest sichuan province,as an example in this paper.

This paper,in light of the system science and geomorphology,uses geomorphic information entropy which can be used to indict the characteristics of evolution of landforms to study debris flow gully and make risk assessment of debris flow gully.

Model test of valley-shaped debris flow motion

This paper mainly discussed and assessed the hazard levels of debris flow valleys based on the data of field investigation and high-resolution remote sense image identification.
