Hydrological Modelling of Slope Stability

Abstract:  Extreme rainfall events are the major driver of landslide occurrences in mountainous and steep terrain regions around the world. Subsurface hydrology has a dominant role on the initiation of rainfall-induced landslides, since changes in the soil water content affect significantly the soil shear strength. Rainfall infiltration produces an increase of soil water potential, which is followed by a rapid drop in apparent cohesion.

A parallel computational framework for the simulation of variably saturated flow based on the Cellular Automata concept using CUDA architecture

Abstract: A simple and efficient parallel computational framework is presented for the simulation of variably saturated flow in porous media. In this modeling approach the Cellular Automata (CA) concept is implemented. The computational domain is thus discretized with a regular grid and simple rules govern the evolution of the physical phenomena. The inherent CA concept simplicity and its natural parallelism make the parallel implementation of algorithms very efficient, especially for the simulation of large scale phenomena. Read more
