Fuzzy Logic Implementation of Vulnerability Assessment in a Coastal Aquifer of Northern Sicily

Aquifers can be defined as complex ecological systems. Their description is closely influenced by geometrical and geological parameters, which portray the hydrogeological behaviour of underground This paper reports a contribution to assessing groundwater contamination risk in particular Sicily sector, where deterministic approaches have methodically assessed mapped vulnerability quality groundwater. In detail, the coastal area of Acquedolci (Northern Sicily), already intensely surveyed frame interdisciplinary projects on geological risk, implementing models systems been experimented, also considering fuzzy logic. Cartography issues are here presented compared, with regard effect stochastic elements (i.e. “depth to water”), locally characterized variability for simultaneous climate, overdraft, irrigation sea encroachment. The authors show how logic, applied to vulnerability settings, contributes better comprehension passive scenery offered aquifers Acquedolci area.
