Short summary

Coastal areas are highly populated and seawater intrusion endangers the already scarce freshwater resources. We use, for the first time, a geophysical experiment called cross-hole electrical resistivity tomography to monitor seawater intrusion dynamics. The technique relies on readings of rock and water electrical conductivity to detect salt in the aquifer. Two years of experiment allowed us to reveal variations in aquifer salinity due to natural seasonality, heavy-rain events and droughts.
