Differences in Results Yielded by Different Approaches Adopted for the Interpretation of a Rapid Flowslide in a Pyroclastic Cover

The paper interprets a case-history of rainfall-induced flow-like landslide in pyroclastic soils by adopting different approaches in modelling the boundary value problem. In particular, two adopted approaches take into account both rainfall and evaporation effects, while the simplest one disregards the phenomenon and considers only the effects of the rainfall-history. The work shows how increasing model complexity in accounting for most of influencing meteorological factors permits predicting a more pronounced hydrological singularity at the landslide time.
