Modeling a Metamorphic Aquifer through a Hydro-Geophysical Approach: The Gap between Field Data and System Complexity

The productivity of metamorphic aquifers is generally lower than that the more common alluvial and carbonates ones. However, in some Mediterranean areas, such as Calabria region (Italy), water scarcity combined with presence extensive bodies requires development further studies to characterize hydrodynamic properties these groundwater systems order achieve their sustainable exploitation. interest this goal becomes even greater if climate change effects are considered. purpose study was provide geological-structural hydrogeological numerical modeling a aquifer, using direct indirect data measurement, large area Sila Piccola Calabria. characterization crystalline-metamorphic constituted by granite rocks, extremely complex. MODFLOW-2005 model used simulate flow phenomena obtaining hydraulic conductivity values 2.7 × 10−6 m/s, which turned out be two orders magnitude higher those obtained from interpretation slug-tests performed area. mathematical also able estimate lateral recharge neighboring deep aquifer providing significant supply system under investigation.
