COUPLING 3D HYDROGEOLOGICAL MODELLING AND GEOCHEMICAL MAPPING FOR AN INNOVATIVE APPROACH TO SUPPORT MANAGEMENT OF AQUIFERS



Abstract:
A methodological approach to assess the hydrogeological feature in complex hydrogeological situations is proposed. It provided a hydrogeological 3D modelling, supported by hydrogeochemical mapping and integrated interpretation of available data. The proposed methodology was applied to the strategic aquifer of the Nurra district (NW Sardinia, Italy). The finding of this work highlighted that structural history of the Nurra district exerts a relevant control on the hydrogeology and hydrochemistry of groundwater. The local connection of Triassic and Jurassic aquifers was proposed. The knowledge-base system will provide a suitable and effective tool for understanding and monitoring the dynamics of pollutant transfer into groundwater to better manage water resources and mitigate desertification processes.
