22 nd Salt Water Intrusion Meeting: Salt Water Intrusion in Aquifers: Challenges and Perspectivestemperature of the third water type seem dueto the interaction water-carbonate rocks,defining an almost steady fluid system at highsalinity, even at not particularly hightemperature.The completion of surveys, which will beenlarged thanks to deep geophysicalcampaigns, should be sufficient to clarify thesource of third-type water, the source ofpressure forced out these waters, justifyingthe steady characteristics of their outflows.REFERENCESBogli, A., 1964.

22 nd Salt Water Intrusion Meeting: Salt Water Intrusion in Aquifers: Challenges and PerspectivesUNDERSTANDING THE ORIGIN OF SALINIZATION OF THE COASTALAQUIFER OF SOUSSE (TUNISIA) USING GEOCHEMICAL AND ISOTOPEINVESTIGATIONSHAMOUDA, Mohamed Fethi Ben; CARREIRA, P.; EGGENKAMP, H.;MARQUES J.M.f_benhamouda@yahoo.frCNSTN, Tunisia; ITN, Portugal; UTL, PortugalCNSTN, UHGI, Technopark of sidi Thabet, 2020, TunisiaAbstract. Simulation of saltwater transport is an essential tool to understand environmentalproblems such as saltwater intrusion in coastal aquifers,landfills leakage, radioactivedisposals in salt rock formations and subsurface dissolution of evaporites. Subsaturatedgroundwater in contact with evaporitic rock formations results in rapid subsurfacedissolution or subrosion of evaporites. The process leads to both karst development andsalinization of aquifers. Depending on the geological setting the subrosion may causewidespread land subsidence. The factors controlling formation and shape of deep-seatedsubrosion, however, are poorly understood. A crucial point is to understand the role andpathways of water subsaturated with NaCl, or CaSO4 and its driving energy, such asprovided by a hydrostatic head differences, or density gradients, which causes groundwaterto flow through the system. To address the problem, results of experiments and modelingapproaches are presented, including: (1) a combination of flow tank and modelingexperiments to study the effect of density-driven flow in heterogeneous media, and (2) a seriesof 2D density-coupled solute transport simulations along an approximately 1000-m long and150-m deep 2D cross section, which represents a setup of two aquifers connected bysubvertical normal fault zones. The resulting high contrasts in groundwater density weresimulated at both laboratory and field scale with a numerical model based on Mixed FiniteElements for the fluid flow problem and a combination of Discontinuous Galerkin FiniteElement and Multi- Point Flux Approximation methods for the transport. The experimentalflow tank data are presented as benchmark problems to evaluate numerical codes. Simulationresults of the 2D cross section indicate that the upconing process of saline groundwater intothe main aquifer occurs under different distributions of subsurface parameters and hydraulicboundary conditions. The simulations also revealed that the most sensitive factor for thedissolution rate is the structure or dip of the halite formation, with an increase of dissolutionrate with increasing dip. As a result of the increased density of the brine, an independent flowdynamic develops that follows the direction of the dip.Keywords: Geochemistry; isotopes; groundwater salinity; Tunisia105
