This paper presents one- and two-dimensional simulations of the water infiltration process on unsaturated soils by using a coupled infiltration-deformation model. Two examples are presented for the one-dimensional infiltration analysis. The first example simulates the infiltration process on a homogenous soil, and the second on a stratified soil composed of two different layers. For both cases, a one-meter column of soil was used to conduct a parametric study by assuming different values of rainfall intensity. It was found from this analysis that the one-dimensional infiltration process on the homogenous soil is highly dependent on the rainfall intensity (I) / permeability (ksW) ratio, and for the stratified soil, the infiltration process was controlled by the soil with less permeability. Finally, one example is presented to study the bi-dimensional infiltration process on a slope subjected to a high-intensity rainfall, where the localization of the failure surface is presented. The results of this analysis show the advantages of this methodology to study soil structures subjected to infiltration processes.
