A hydrogeological modelling, supported by geological and hydrogeochemical data was performed. The proposed methodology was applied to the strategic aquifer of the Cixerri area (SW Sardinia, Italy). The knowledge-base system will provide a suitable and effective tool for understanding and monitoring pollutants transfer dynamics into groundwater to better manage water resources and mitigate desertification processes. In particular, this study aims to evaluate the potential risk of nitrate pollution in aquifers from agricultural practices by combining intrinsic aquifer vulnerability to contamination.
