MAPPA DELLA SUSCETTIBILITA’ FRANA MEDIANTE UTILIZZO DELLA LOGICA FUZZY

The present paper proposes a new methodology to characterize the landslide susceptibility of Reggio Calabria territory. The values obtained were classified into five categories: very low, low, medium, high and very high, and were than exported into GIS environment to produce a landslide susceptibility map. The principal objective of the proposed study is to identify the sections of the road network exposed to landslide hazards starting from the susceptibility map. To this aim, a fuzzy system was designed with 2 input, 15 rules “if-then” and 1 output representing the “level of attention” for the considered transport infrastructure, being a higher value of attention level correspondent to a higher landslide hazard. From the obtained results it is possible to notice that the most relevant roads in terms of connection, as the highway A3, the road SS106 and other roads linking the Ionian Coast to the Tirrenic Coast, are those displaying the highest level of attention.
