Flow Simulation in Unsaturated, Heterogeneous Soils

Porous media flow models are applied in important areas of interest, including environmental studies or industrial applications. In this case, large-scale experiments are usually expensive, or even impossible, so computer simulations should replace them. Here we focus on the numerical simulation of a flow in an unsaturated, heterogeneous soil. We summarize briefly some results concerning the modeling aspects and describe a numerical approach for solving these kinds of problems. Simulation results are presented at the end of the paper.
