Abstract: Abstract Coastal aquifers are vulnerable to saltwater intrusion (SWI) due to several drivers particularly increased water demand and groundwater overexploitation associated with population growth, reduced groundwater recharge, and lately climate change. This study examines the status of SWI in four data scarce coastal aquifers located along the Eastern Mediterranean by assessing how water cycle seasonality, water deficits, and changes in land use and land cover (LULC) have contributed to increased salinity. A framework that combines field monitoring with hydro-geochemical techniques, as well as multivariate and inferential statistical analysis was used to identify the main SWI drivers at play at each aquifer. The overall assessment showed that all four pilot areas exhibited signs of salinization with different severities. The current state of the aquifers ranged from slightly saline (TDS
