With electrical resistivity tomography (ERT) method, a region’s subsoil can be characterized, leading to pseudo-section maps that allow to differentiate between freshwater and saltwater cavities. In this study, ERT method was applied in the Riera de Sant Pol de Mar, in two different surveys a month apart; which permitted to measure a strong variation between both and track the aquifer’s underground evolution. This allowed the observation and analysis of the seawater intrusion phenomenon. If combined with additional methods or information, a better understanding of the diverse processes that occur beneath the aquifer’s surface could be achieved5 p.application/pdfengcc-by-nc-nd (c) Garcia, 2022http://creativecommons.org/licenses/by-nc-nd/3.0/es/Intrusió marinaTomografia elèctricaTreballs de fi de grauSaltwater encroachmentElectrical tomographyBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
