Abstract: The free water table of the solid dune mass of "Bouteldja" belongs to the "Mafragh" hydro system. Its mode of layer and its boundary conditions hinders the management of this tablecloth particularly in period of dryness. Numerical modeling using the software MODFLOW-Waterloo-Canada allowed to establish the hydrous assessments of 21, 16 and 8 Hm3, after the simulation of the scenario of natural refill of the tablecloth average and the cyclic dryness 5, 10 and 20 years. These evaluations indicate the tablecloth levels of exploitation, which must imperatively be respected to maintain the hydrodynamic balance and the eco-systems Eastern "Numidie" wetlands associated with this tablecloth.
