Popis: International audience; The region of ace that is given a heavy responsibility in the socio-economic developmentof Morocco. This development implies a significant increase in water needs in the coming years84for both drinking water supply and for irrigation and industry. This sector, like the other regionsof Morocco, has experienced a significant decrease in water intake in quantity and quality. Thissituation has led to the reduction of agricultural productivity and the degradation of severalecosystems. However, this basin has an aquifer system consisting of a set of uneven aquifersthat can offer a natural regulating capacity that makes them valuable to ensure a safe and steadysupply. The reserve also makes it possible to meet seasonal needs through temporary overexploitationto the extent that replenishment is possible.The so-called synclinal study area of Essaouira is part of the coastal zone of the basin withan area of approximately 1418 km2. It is limited to the North by Jbeb Hadid, to the South byTidzi River, to the East by the reliefs of South Chiadma, reliefs of North Haha and by the Tidzislide, and to the West by the Atlantic Ocean.Geo-electrical prospecting by vertical electrical soundings is a geophysical method that,applied in hydrogeology, will provide information on the geometry of possible reservoirs, theirlithological nature and the spatial evolution of these characteristics. The interpretation of theresults of this study, in correlation with the mechanical drilling, made it possible to stand outfrom the quantitative and qualitative maps, the different variations of apparent resistivity of thegeological layers constituting the aquifer and aquiclude. The analysis of these maps shows thatthe area around the Qsob River is of interest from a hydrogeological point of view.
