3D hydrogeological modelling supported by geochemical mapping as an innovative approach for management of aquifers applied to the Nurra district (Sardinia, Italy)

A hydrogeological 3D modelling, supported by hydrogeochemical
mapping and integrated interpretation of available data, was
performed. 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 pollutants transfer
dynamics into groundwater to better manage water resources and mitigate desertification processes.
