Kinematics of slow-moving active landslides

We experiment the application of 3D numerical modelling techniques for the analysis of the kinematics of slow-moving active landslides. The activity assesses the hazards posed by slow-moving landslides, determines the factors controlling the slope processes, investigates the potential evolution of the active slopes, and helps selecting appropriate slope mitigation strategies.

We exploit modern numerical modelling techniques based on finite element methods, using two-dimensional (PLAXIS-2D) and three-dimensional (PLAXIS-3D, COMSOL Multiphysics) commercial software. We calibrate and optimize our numerical models using landslide-monitoring data acquired using traditional and new techniques, on the ground, from the air, and from space.

The numerical models can be used to predict the kinematical evolution of the landslides.
