The intrusion of seawater in coastal aquifers Greece is a particularly widespread phenomenon. coastline has length 15,147 km. Once groundwater resources are contaminated, remediation strategies difficult, costly and time consuming. In this paper three aquifer systems Peloponnese studied. Initially the main ions cations were calculated for aquifers. According to results from hydrochemical analyzes Na+,Mg2+, Ca2+, SO4-2, Cl- have high values affected by into It estimates vulnerability seawater. Using Geographical Information Systems (GIS) software, maps prepared presentation each parameter GALDIT method. factors that affect basically presented 6 letters acronym GALDIT. analysis as follows: Groundwater occurrence (aquifer type: unconfined, confined, leaky confined), Aquifer hydraulic conductivity, depth Level above sea, Distance shore (inland distance perpendicular shoreline), Impact existing status sea water area Thickness aquifer. final map emerged study shows Peloponnese. show system Larissos presents lower compared other two systems.

Seawater intrusion (SWI) into coastal aquifers poses a significant environmental problem, and identifying an effective method to assess its extent is challenging. This study introduces for accurately delineating the of SWI in Ghiss-Nekor aquifer, using dual approach hydrogeochemical analyses geospatial technologies. We used several geochemical markers, including four ionic ratios (Cl-/HCO3-, SO42-/Cl-, Na+/Cl-, Mg2+/[Mg2++Ca2+]) along with two indices (GQIswi SMI). These markers were interpolated subsequently overlaid GIS-based overlay analysis, enabling us generate accurate map pinpointing areas affected by SWI. The reveals that affects roughly 20 % investigated region, 70 these cases found within 2 kilometers coastline. detection saline water as far 5 inland, explained aquifer's geological model, points emanating from Souani area, infiltrating through coarse sand gravel located above impermeable deep clay-marly strata. outcomes validate our offer essential data about SWI's scope. Such insights are indispensable policymakers Al Hoceima area forge groundwater management strategies response climate change-induced challenges like diminishing resources reduced rainfall.
