The paper presents the numerical inverse analysis of a well-documented slow-moving landslide in Southern Italy which has been active in the 70s along the banks of an artificial reservoir servicing a hydro-electric power plant. A numerical procedure was adopted to predict movements of active landslides along pre-existing slip surfaces related to changes in the groundwater regime of the affected slope. The analysis was used to: (1) evaluate the absolute and relative importance, for the observed kinematic behaviour of the phenomenon, of the two triggering factors of the landslide: rainfall and changes of the reservoir’s level, (2) assess the effectiveness of different mitigation strategies on the basis of numerical predictions based on the calibrated model of the phenomenon.

Abstract

The paper presents the numerical inverse analysis of a well-documented slow-moving landslide in Southern Italy which has been active in the 70s along the banks of an artificial reservoir servicing a hydro-electric power plant. A numerical procedure was adopted to predict movements of active landslides along pre-existing slip surfaces related to changes in the groundwater regime of the affected slope. The analysis was used to: (1) evaluate the absolute and relative importance, for the observed kinematic behaviour of the phenomenon, of the two triggering factors of the landslide: rainfall and changes of the reservoir’s level, (2) assess the effectiveness of different mitigation strategies on the basis of numerical predictions based on the calibrated model of the phenomenon.
