Effects of the Climatic Conditions on the Behaviour of a Slow Landslide in Clay

Abstract

This report contains the results of some numerical simulations performed in order to furnish a methodological approach aimed to understand the influence of the climatic conditions on the behaviour of a slow earthflow. The analyses have been performed using the numerical model adopted by the FEM code VADOSE/W (Krahn, 2004), which allows to assess the interaction existing between the ground surface of a soil deposit and the atmosphere due to the alternating climatic conditions. Moreover, a scenario of the long-time future behaviour has been estimated thanks to the results coming from the analyses performed by the COSMO-CLM climatic model.
