Generally, in classical studies that concern the hydrogeological modeling of aquifers, soil properties are represented through a single homogeneous or heterogeneous domain with equivalent parameters that are not representative to the hydrogeological reality but that fit the observed data by means of a calibration process. A more accurate modeling of the lithologic, geological and structural characters of an aquifer is of extreme importance when simulating fluid flow and solute transport, in order to improve the reliability of the numerical simulations. On the other hand the information available for the setting up of an hydrogeological model I'S subjected to uncertainties and ambiguities due to not univocal interpretations or to uncertainties linked to the methodologies of measurement of the variables of interest. This implies the impossibility to represent the hydrogeological reality with an unambiguous solution even if optimal. The present paper is aimed at characterizing hydrogeologically a coastal aquifer. The presented methodology is finalized at identifying not a univocal model but a set of "equifinal" solutions.
