Abstract

The AA. focus on the region of Campania which contains highly urbanized piedmont areas particularly vulnerable to flooding. Using geomorphological analysis they recognized active alluvial fans while stratigraphic analysis together with statistical analysis of the morphometric variables was used to classify the fans in terms of the transport process involved. The results indicate that the best discrimination between debris flow (Df) and water flood (Wf) processes is achieved by means of 2 related variables, one for the basin (feeder channel inclination, Cg) and one for the fan (fan length, Fl). The probability that an unclassified fan belongs to group Wf is computed by applying a logistic function in which a P value indicates that a basin/fan system belongs to group Wf. This important result led to the classification of the entire basin/fan system data.
