Abstract

On October 1st 2009, after a very rainy season, a violent rainstorm poured down Giampilieri, in North-Eastern Sicily with damages to property, buildings, roads, bridges and moreover, loss of human lives. The main focus of this work concerns the analysis of debris volume that has been carried out during this event through the definition of methodologies and determination of techniques that can be applied to evaluate assessment, define crisis scenarios and predict situations of possible debris-mud flows. Here, a series of open-source GIS-based algorithms using spatial analysis has been used in order to perform the calculation of debris-mud flows volume moved during rainstorm. By comparing the volume and run out of past events Rickenmann(Nat Hazards 19(1):47-77, 1999), it is possible to identify empirical site-specific formulas to estimate run out distance of potential events. The analysis issue helps in assessing risk for establishing policies of land planning and civil protection activities. © Springer-Verlag Berlin Heidelberg 2013.
