Abstract

Groundwater within coastal aquifers is considered a very sensitive\backslashnnatural resource since its quantity and quality is threatened by\backslashnanthropogenic activities as well as global and climate changes. The\backslashnmajor environmental hazard with respect to coastal aquifers is the\backslashnphenomenon of seawater intrusion, and is more pronounced in the\backslashnMediterranean basin. In the light of smart management of such\backslashnhydrogeological systems, GALDIT index was introduced in the form of a\backslashnnumerical ranking system that aims to assess the vulnerability of such\backslashnaquifers to seawater intrusion. This paper provides an application of\backslashnGALDIT vulnerability index for a typical Mediterranean alluvial aquifer\backslashnunder variable hydrogeological conditions in different research periods\backslashn(1992 and 2004). The results proved the significance of the piezometric\backslashnconditions of the aquifer with respect to its vulnerability to seawater\backslashnintrusion.
