Abstract
Previous experience at a regional scale has demonstrated that the greater the possibility of analyzing and managing information utilized for saltwater intrusion modeling in coastal aquifers, the more comprehensive and reliable the end results are likely to be. The contribution offered by Geographical Information Systems (G.I.S.) for achieving this goal is crucial.
A G.I.S. allows to acquire, store, process and represent spatial information in real time and in a form suitable for further use in different application contexts. A wide range of problems can be addressed within the philosophy of a G.I.S., thematic mapping, land planning, environmental impact studies, natural resources management, location of environmental risk areas, demographic studies, modeling.
The information acquired during earlier hydrogeological studies in the Capoterra alluvial plain have been organized into a G.I.S. for the purpose of modeling saltwater intrusion. The paper describes the modeling procedure adopted.
