Abstract

In the paper a modelling of a real debris flow in the Enna area in the south of Italy is described. Starting from the study of the geological framework and the historical background for landslides of the Enna district, the research has focused on the causes triggering the landslides. In order to study the performance of debris flow, the real case of 1st-2nd February 2014 which affected Enna city has been modeled. The event caused damage to private buildings and above all the interruption of the main infrastructure connecting Enna city at the motorway, due to the material on the road. The modelling of the real debris flow using a mono-phase model (FLO-2D) was carried out in order to investigate the global dynamic of the event. The study allows to acquire a better knowledge of the hydraulic parameters that can be used in other modelling events for areas with a similar soil composition in order to assess the most appropriate mitigation works, reducing damage to structures and infrastructures.
