The studied area is located along the peri- Tyrrhenian zone of the central Apennines, between the Mesozoic and Cenozoic carbonate platform sequences of the Aurunci Mountains and the volcanic sequences of the Roccamonfina. A multi-disciplinary approach was followed, using newhydrogeological surveys, the interpretation of strat- igraphic logs of boreholes and water wells, and geophysical data—seismic sections, shear-wave velocity (Vs) crustal mod- el and gravimetric model. The collected information allowed for construction of a conceptual hydrogeological model and characterization of the hydrothermal system. The Suio hydro- thermal system is strongly influenced by the Eastern Aurunci hydrostructure. Along the southeastern side, the top of the hydrostructure sinks to −1,000 m relative to sea level via a series of normal faults which give origin to the Garigliano graben. Geological and hydrogeological data strongly suggest the propagation and mixing of hot fluids, with cold waters coming from the shallow karst circuit. The aquitard distribution, the normal tectonic displacements and the frac- turing of the karst hydrostructure strongly influence the hy- drothermal basin. Carbon dioxide and other gasses play a key role in the whole circuit, facilitating the development of the hydrothermal system. The current level of knowledge sug- gests that the origin of the Suio hydrothermalism is the result of interaction between the carbonate reservoir of the Eastern Aurunci Mountains and the hot and deep crust of this peri- Tyrrhenian sector, where the Roccamonfina volcano repre- sents174 12 - PublicationOpen AccessA Macroscale Hydrogeological Numerical Model of the Suio Hydrothermal System (Central Italy)(2019-05-16)
; ; ; ; ; ; ; ; ; ; ; ; ;The complex behaviour of the Suio hydrothermal system (central Italy) and its potential exploitation as a renewable energy source are still unclear. To quantitatively evaluate the geothermal resource, the Suio hydrothermal system has been investigated with a hydrogeological numerical model that couples fluid flow, thermal convection, and transport of diluted species inside a hybrid continuum-discrete medium. The numerical model, calibrated and validated with available and new experimental data, unveiled the complex behaviour of the hydrothermal system. The normal tectonic displacements, the fracturing of the karst hydrostructure, and the aquitard distribution strongly influence the hydrothermal basin. In particular, a dual fluid circulation, sustained by steady-state thermal and pressure gradients, modulates the hydrothermalism at the several springs and wells. The presence of a medium to a low-temperature reservoir allows for potential exploitation of the geothermal resource.103 80 - PublicationRestrictedHydrogeological study and numerical model of the Suio-Castelforte hydrothermal area (central Italy)(2016)
; ; ; ; ; ; ; ; ; ; ; ; ; A numerical simulation has been performed through the natural geothermal system of Suio-Castelforte (LT) in order to investigate the hydothermal area and assess its geothermal potentiality. Starting from geological and hydrogeological data a 2D conceptual model has been built. For numerical purpose, the latter idealizes and simplifies the natural system. The area has been affected by a temperature gradient, from low to medium enthalpy, related to the Quaternary volcanism. By a FEM (Finite Element Model) method, using the COMSOL MULTIPHYSICS® software, a homogeneous and isotrope media have been assumed, simulating the groundwater flow and simultaneous heat transfer. Using the porous media approach, Darcy and heat transfer laws have been applied in steady-state conditions. The results have been compared with the collected data and bibliography.104 5
