This paper deals with the landslides activated by piezometric level changes owing to rainfall. Generally, the main type of movement experienced by these landslides is a translational slide with low displacement rate. In addition, deformations are essentially concentrated within a narrow shear zone above which the unstable soil mass moves as a rigid body. In view of this evidence, a simple approach based on a sliding block model was recently proposed by Conte et al. (2017) for a preliminary evaluation of the mobility of these landslides. This method relates landslide movements to rain recordings. This constitutes a significant advantage for land protection purposes because future displacements could be directly predicted from expected rainfall scenarios. In the present paper, a case study is analyzed to assess the predictive capability of the above-mentioned approach.

Abstract
This paper deals with the landslides activated by piezometric level changes owing to rainfall. Generally, the main type of movement experienced by these landslides is a translational slide with low displacement rate. In addition, deformations are essentially concentrated within a narrow shear zone above which the unstable soil mass moves as a rigid body. In view of this evidence, a simple approach based on a sliding block model was recently proposed by Conte et al. (2017) for a preliminary evaluation of the mobility of these landslides. This method relates landslide movements to rain recordings. This constitutes a significant advantage for land protection purposes because future displacements could be directly predicted from expected rainfall scenarios. In the present paper, a case study is analyzed to assess the predictive capability of the above-mentioned approach.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
