Abstract
The hydrological and hydrogeochemical study of the catchment area of Wadi El Arab and the
dam Babar, enabled us to have an outline on the qualitative state of the water reserve of
the region. The hydrological study shows that the zone of study is characterized by a semi
arid climate, with a very weak flow on the catchment area of Wadi El Arab , which
translates conditions of food and very unfavorable flow in particular a strong evaporation.
The hydrogeochemical study of water of the stopping shows that the evolution of the
chemical elements according to time emphasizes that strong calcium and sulphate
concentrations are dependent the presence of evaporitic or saliferous formations like the
gypsum.
