Modelling of Debris Flows and Flow Slides

Pastor, Manuel / Merodo, Jose Antonio Fernandez / Quecedo, Manuel / Herreros, Maria Isabel / González, Elena / Mira, Pablo

This paper presents a numerical model which can be used to simulate phenomena such as flowslides, avalanches, mudflows and debris flows. The proposed approach is la- grangian, and balance of mass and momentum equations are integrated on depth. Depending on the material involved, the model can implement rheological models such as Bingham orfrictional fluids. A simple dissipation law allows the approximation of pore pressure dissipation in the sliding mass. Finally, some applications are presented.
