Advanced Hydrogeological and Geothermal Systems (AHGS)

The Advanced Hydrogeological & Geothermal Systems Research Group (SHGA) studies the hydrogeological dynamics and coupled thermo-chemical regime of shallow and deep aquifers through fully three-dimensional, variable-density, multiphase reactive-transport modelling constrained by georeferenced geochemical databases, high-resolution subsurface temperature time-series, down-hole sensor networks and remote-sensing products. Stable- and radio-isotopic tracers are integrated to resolve groundwater provenance, age distributions and contaminant-flow paths. Our study sites encompass (i) heavily exploited urban aquifers, where we quantify geothermal potential, thermal interferences and subsurface properties; (ii) volcanic island systems in Macaronesia, assessing preferential recharge, hydrothermal mixing and nitrogen fluxes; and (iii) water-stressed continental basins.
