Facing geological heterogeneity impact on reciprocal coastal systems

Coastal zones are increasingly demanded spots for human settlements and economic development. In these areas, aquifers are subjected to the threat of landward entrance of seawater caused by overexploitation of fresh groundwater resources. In some contexts, a coeval groundwater flow of freshwater seaward can also take place, often linked to the surficial discharge of ephemeral streams. Understand the interactions between this two reciprocal flows in coastal aquifers is needed to be able to characterize the freshwater-saltwater interface and the effects on rate of submarine groundwater discharge
