Landslide Hazard Assessment Model for Slope Stability Analysis

Soil moisture dynamics is a complex phenomenon that depends on the atmosphericconditions, the geomorphological characteristics of the region under study, and thecorresponding land use. It can be formally described by a diffusion model based onDarcy’s law and the law of mass continuity. In this work, the obtained numericalsolution of the hydrological model has been exploited to evaluate the soil moisture ina given region and build a risk map for the slope stability of this region. More in detail,the infinite slope model from slope stability analysis has been used for evaluating thesafety factor and constructing the corresponding quantitative hazard maps. Someresults of the proposed method applied to a real case study are shown and discussed.
