Short summary
Due to the widespread salinity in coastal zones, freshwater supplies are now under pressure. This study analyzes the recharge and salinity sources of coastal groundwater (brine, saline, brackish, fresh), as well as salinization and freshening processes, using hydrochemical and isotopic methods. The evolution of saline groundwater is studied using sedimentary characteristics as multiple lines of evidence. This study can be used to better understand groundwater evolution in the coastal zone.
