GNGTS 2022 Sessione 1.3 179 circulation problems. In addition, the preliminary results obtained for a generalised vertical sectionexamining regional karst aquifers showthe strong control of basincompartmentalisation on fluid outflows (i.e., water, hydrocarbons, CO2). Finally, the coupling of groundwater flow and heat transport in a heterogeneous anisotropic domain will be the next implication of the current study. Indeed, if the basin is characterized by more permeable lithology and the topography by high reliefs (e.g. Smith et al. , 1983), the near- surface thermal regimes can be highly influenced by active groundwater flow systems. As done in the central Apennines, where gravitational potential energy dissipation and geothermal heating have been calculated (e.g. Chiodini et al. , 2013), heat redistribution will be addressed by considering both conduction- and advection-dominated thermal regimes.
