Water Quality At A Karstic Aquifer In The Region Of Tebessa, Northeast -Algeria-

摘要

The Maestrichtian limestones massif of Tebessa's region; shows a complex structure which presents many remarkable forms of karst (Bouakkous). The study of many sources of relief can allow the characterization of important water reserves. The hydrogeological study on the relationship and operation of five sources (Ain Troubia, El Megalib, Gaagaa, Youkous and Ain Sarie) located in different altitudes and spaced fairly large distances. The flow variation is a function of time and the precipitation shows a resemblance characterized by curves generally affected by certain peaks. The followed hydrochemical of the five sources showed the same chemical facies which is calcic to magnesian bicarbonated with predominance of the first facies; except the source of Ain Sari is composed of calcic chlorinated. The evolution of the contents of the chemical elements is due to the increase in the flow of the sources after the period of flood which demonstrates the effect of the behavior of the karst area.
