The flysch formations, due to their lithology, are rarely characterized, as hydrogeological prospecting target. However they are full of significant water resources in the study area located in the west of the city of Tetouan in northern Morocco. These water resources were evaluated relaying on the limits determining and exploring of different aquifers included called "Limited aquifer systems". These aquifers three in number (Numidian system of Zinat, the Melloussa-Tisiren system and Quaternary-Tangier unit system), are characterized by a lithostratigraphic and structural context promoting storage of water. They were identified from: the inventory of water points, effectuation of lithologic and structural maps and geological cross-sections. This was complemented by measurement of groundwater levels and flow releases. So, it could reveal the impact of stratigraphic and structural context of the area on the establishment aquifer systems as well as their limitations.
