Abstract

One of the most frequent landslide triggering causes are rainfalls which can determine such variation in pore pressures to reduce the shear strength and to determine slope instabilities. To realize failure mechanisms, surveys, investigations and analysis are expensive indispensable conditions. Then hydrological models are very useful to define scenarios that could trigger landslides generally classifiable and connected to homogeneous geoenvironmental contexts. Three classes of instabilities are considered: shallow (SH), medium deep (MD) and deep (DD) landslides. The hydrological analysis has been carried out referring to geo-environmental contexts in which landslides, referable to the considered classes, are traceable. For SH the employed procedure consists of analysin
