“…Despite this modest rainfall, the Guir sometimes experiences violent floods. At Tazouguert (2392 km 2 The flows are generally determined by precipitation on the upper basin, breaking more or less downstream, many reach a closed basin: the Sebkha El Mellah, via the Wadi Es Souireg which go down to the North-West to the output of Fourn el Kheneg [REZZOUG et al 2017].…”

To resist against a hostile environment, the oases of Saoura developed ingenious techniques of catchment and sharing of water to exploit the rare and precious waters of the groundwater. But the intervention of modern irrigation techniques has disrupted the entire oasis system inside the oasis such as the spring, the palm grove and the ksar. These techniques have overexploited the groundwater supplying the palm grove in terms of quantity and quality. For centuries, the oases of Mougheul used only the source (with a flow of 25 dm3∙s−1 in 2001) which is inside the oasis to irrigate the parcels and herds. After the year 2005, the state decided to supply the city of Bechar with drinking water through the catchment field of Mougheul through five modern boreholes, which had a profound impact on the oasis, its surroundings, and the whole artesian source. In this work, we study the impact of the use of modern catchment systems on the water source and the life of the Mougheul population. By interviewing farmers and landowners about the impact of groundwater scarcity on the oasis. This allowed knowing the current state of the oasis and the reasons for its deterioration.

The present study focused on the hydrochemistry of groundwater in Kerzaz and Beni Abbes in Saoura oases (southwest of Algeria) to assess the quality of groundwater for determining its suitability for drinking and irrigation purposes. The study area experiences a hyper-arid climate characterized by low rainfall 50-100 mm/year and excessive drought. Groundwater samples were collected from 24 locations to ensure a good spatial distribution to cover all the study areas. Standards laboratory methods were used to determine physicochemical groundwater properties. The result for this study showed that the water was to be found unsuitable for drinking purposes except for few samples in Kerzaz and Beni Abbes. Except for PI values, all other physicochemical parameters (EC, SAR, MAR), and according to the US salinity diagram, groundwater in Kerzaz was to be found satisfactory for irrigation especially if the soil permeability is improved and the leaching is guaranteed by applying extra frequently irrigation. In Beni Abbes, 58.33% of water samples show that water can be used if rapid permeability is guaranteed, which is the case in Beni Abbes soils, and 25% present medium salinity and low to medium alkalinity (C2S1, C2S2, C3S3) and only the natural spring presents a low salinity and low alkalinity C1S1 permitting the use of water for irrigation with most crops on most soil. Piper diagram indicates groundwater in Kerzaz belongs to CaCl type, while in Beni Abbes four types were recognized, NaCl, CaMgHCO 3 , CaCl and mixed CaCl type with 16.66%, 8.33%, 41.66% and 33.33%, respectively.
