The aim of this work was to identify the potentially groundwater-producing areas of an environment characterized by a multilayer aquifer in the Gar Djebilette region, far southwest Algeria. Thus, landsat 8 and Aster images were processed merged and interpreted to extract fractures from the study area. Drilling parameters were also used in this study. Their integration in two multi-criteria analyses made it possible to produce, on the one hand, the aquifer potentiality map according to the method of JOUDA et al (2006) and, on the other hand, the groundwater productivity map according to the salay approach (2003).
Key words: multi-criteria analyses, groundwater productivity map, the aquifer potentiality map
