ABSTRACT
Background: Groundwater is often threatened by contamination from different types of pollutants. Prevention against pollution is an important step in which scientists provide more and more effort, by studying the vulnerability of aquifers. This region occupies an important place in Moroccan territory, as well by its geographical location and its water and agricultural potential. At the causse of middle Atlas, the water table is located in a fractured carbonate reservoir and karstified having high fracture permeability which probably makes it vulnerable to anthropogenic pollution. Objectives: The study of vulnerability in areas prone to pollution of various kinds is very important for the management of water resources. Our study aims to map this phenomenon using GIS and modeling methods in the causse of middle Atlas (region El Hajeb : Ifrane) (e.g. DRASTIC.). Methods: The vulnerability of groundwater reflects the way in which it can be achieved by pollution from the soil surface. The DRASTIC method is the most method used to assess the vulnerability and spatialize over large areas. The parameters taken in this method are: the depth of the water (D), net recharge (R), the materials of the aquifer (A), soil type (S), topography (T) the impact of the unsaturated zone (I) and the hydraulic conductivity (C). Comparison with other methods like (COP, EPIK, PI) was also performed in this analysis. The study data were acquired and converted to several sources in the form of thematic maps through the use of GIS, due to the very large mass of data needed for this treatment. Results: The results are presented as thematic maps. The initial diagnosis revealed that it is an environment with medium to low topography, and a karst lithology favorable to the development of high permeability may actually affect the quality of groundwater. Indeed, analysis of the situation of the causse El Hajeb - Ifrane allowed deducing that the vulnerability to pollution of the groundwater is higher in the southern area where the majority of settings are favorable to such degradation. Conclusions: The completion of the study by the development of map of risk of groundwater in this region will be a very important tool to help protect the groundwater and for good water resources management and soil in the region.
