Abstract:

The plain of El-Outaya is in arid zone in southern Algeria. The groundwater are characterized by an Important and variabilityin its salinity. This work is presented to improve knowledge on these waters by proceeding to their statistical andhydrochemical classifications. Method C.A.H (hierarchical ascending classification) takes of three tendencies based on theimportance of the mineralization. The salt rocks are responsible of this height salinity. Concerning the hydrochemicalsynthesis, the statistical information is confirmed. There is three dominant groups.
