A general two phase depth integrated model considering pore water pressure and dewatering

Debris flows can be considered a type of landslide with large velocities and long run-out distances. There are many types debris flows, depending on the properties solid fluid components mixture. The triggering propagation studied using single 3D mathematical model. computational cost very high because their length, depth-integrated models provide good combination accuracy cost. Both combined in analysis, for initiation at singular points where more is wanted. As chain strength never higher than that weaker link, we have to ensure all accurate enough joint This paper deals new model which take into account changes caused by dewatering flow.
