Effect of vegetation on the triggering of shallow landslides using CRITERIA-3D
Effect of vegetation on the triggering of shallow landslides using CRITERIA-3D
The paper deals with an agro-hydro-mechanical model aimed at obtaining time-varying susceptibility maps for rain-induced shallow landslides, including the effect of different types of vegetation in their seasonal life cycles. The model includes a slope stability analysis based on the limit equilibrium method applied to an infinite slope. The mechanical part of the model has recently been implemented in CRITERIA-3D, a method originally developed to calculate the water balance in a cultivated area. The effect of roots is accounted under both hydrological and potentially mechanical point of view (neglected in this note). CRITERIA-3D has been preliminary validated on a test site slope and then it has been applied to two sample areas in the Emilia Romagna Region. Both the sample areas had been affected by a huge number of landslides following exceptional rainfall between 16 and 17 May 2023. The results show that the model can capture both spatially and temporally the observed shallow landslides, based on available data on precipitation, soil type, and land use at regional scale.
