Rockfall phenomena are characterised by a strong variability because of the influence of many different controlling factors. We discuss the lateral dispersion of rockfall trajectories stressing its relevance for designe of passive countermeasures and hazard zonation. 3D numerical simulations have been performed through a new software code able to use both a lumped mass and an hybrid (kinematic-dynamic) approach. Parametric modelling has been performed at different spatial resolution using sets of bilinear simplified slopeds characterised by different mean inclination and roughness.

Abstract
Rockfall phenomena are characterised by a strong variability because of the influence of many different controlling factors. We discuss the lateral dispersion of rockfall trajectories stressing its relevance for designe of passive countermeasures and hazard zonation. 3D numerical simulations have been performed through a new software code able to use both a lumped mass and an hybrid (kinematic-dynamic) approach. Parametric modelling has been performed at different spatial resolution using sets of bilinear simplified slopeds characterised by different mean inclination and roughness.
