The Role of Initial Soil Conditions in Shallow Landslide Triggering: Insights from Physically Based Approaches

Figure 10

The triggering mechanisms hypothesized according to the experimental evidences: (a) failure induced by an uprise of a temporary perched water table (for soils with relatively low initial water content); (b) failure induced by the advance of the wetting front (for soils with relatively high initial water content).
