Abstract :

The coastal area of Gharb Basin containing Mnasra Aquifer constitutes the only hydric resource for region in terms of domestic consumption and agricultural demand; which does not cease to increase. In addition, we recorded a sharp drop in the water table relatively to the last two decades, the problem of saline intrusion and an alarming deterioration in its quality that imposes a major management issue. At this level, we resort to the artificial recharge highlighting a set of techniques, tools and methods that can ensure the sustainability of exploitation in a rational framework despite the eventual constraints: Growth of population, extension of agricultural perimeters, and climate change. However, in order to proceed with the application of artificial recharge, the technique and the tools were accordingly chosen. We have to first identify the area or areas that are favorable for recharge; this requires a thorough knowledge of geology, pedology, hydrogeology and water quality. Indeed, the present work focuses on a comparative approach for two models: Numerical (hydrodynamic), using finite elements method and analytical solution (Glover) that has been programmed with C++ Language. Finally, the level of concordance between these solutions in space and time allows localizing the area that presents the best conditions for artificial recharge relative to the â�?�?Flowâ�? and the â�?�?Recharge Timeâ�? needed to offset the hydraulic deficit of water balance of aquifer.
