Application of the GALDIT Method to the Study of Groundwater Vulnerability of the East Mitidja Alluvial Waters

PDFImprimerEnvoyer

Abstract:

For the last thirty years, hydrogeologists have been concerned with the preservation of the groundwater of the Algerian eastern Mitidja. Mania et al. (1985), Toubal (1998), Djabri et al. (2003) and Djoudar and Toubal (2008) have highlighted a saline pollution of the Algiers groundwater. Piezometric maps show a clear and total reversal of sea water flow direction towards the continent reaching water catchments of Boureah and threatening those of Hamiz where Piezometric levels are 16 meters below sea level (ANRH 2006).
