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.

An Object-oriented computational framework for the simulation of variably saturated flow in soils, using a reduced complexity model
Abstract: A simple and efficient computational modelling framework is presented for the simulation of variably saturated flows in porous media, which is not based on a conventional numerical solution of the Richards’ equation. The computational domain is discretised with a regular grid and simple rules govern the flow dynamics. Read more
