Coupled Geophysical and Hydrogeochemical Characterization of a Coastal Aquifer as Tool for a More Efficient Management (Torredembarra, Spain)

The aquifers of the Spanish Mediterranean coast are generally subjected to intense exploitation meet growing water supply demands. result is salinization due marine saltwater intrusion, causing a deterioration in quality pumped, limiting its use for community needs, and not always being well delimited. To prevent deterioration, groundwater control network usually allows precise knowledge areas affected by intrusion but extent saline plumes. Moreover, characterization aquifer systems requires model that defines geometry formations. For this objective, we integrated hydrogeological, hydrogeochemical, electrical resistivity subsoil data establish hydrogeological coastal Torredembarra (Tarragona, NE Spain). In research, have carried out regional local-scale study system define prone (electrical values below 10 Ω·m). obtained results could be used as support tool assessment most favorable withdrawal, enabling protection susceptible intrusion.
