Abstract

Groundwater within coastal aquifers is considered a very sensitive natural resource since its
quantity and quality is threatened by anthropogenic activities as well as climate changes. The main
purpose of this study is to use GIS technique to identify, quantify and assess the aquifer vulnerability to
seawater adopting Galdit new approach for the coastal plain aquifer system of Collo situated in the
Northern-East of Algeria. An influential thematic map such as groundwater occurrence (aquifer type),
aquifer conductivity, depth to groundwater level above the sea, distance from the shore and river, the
impact of existing status of seawater intrusion in the area, and thickness of the aquifer, was generated
using related weight and important rating. Finally, the result of the study shows the high vulnerability
corresponding to the 38.60 %, moderate vulnerability corresponding to 51.13 %, and lower vulnerability
corresponding to the 10.25 % of the total area.
