摘要:This work is part of a research program of the division . water and soil . in the center of scientific and technical research on arid regions (CRSTRA). It focuses on the upwelling water problem in the valley of Oued Righ (South- east Algeria). Increased demand for water in the oases of Algerian Sahara has led to an important augmentation in the exploitation of groundwater [1]. Moreover, the geomorphologies of the area, insufficient disposal of drainage water and the decontamination have caused, in recent years, the increase of water upwelling's areas. This has harmful effects on human and his environment. Besides, the studied region is one of the oldest cultivated lands in Algerian Sahara. A collector channel of drainage and wastewater has been realized in 1925 to drain the overage water from oases. Currently, with increasing water demand (population and development), the question of water upwelling becomes more acute. Thus, a census operation about affected areas by this phenomenon has identified twenty sites; the determination of water's physicochemical parameters of identified sites gives salinity values oscillating between 6 and 70 g / l. the latter vary depending on the nature and feeding mode of these areas
