This site is today subject to progressive anthropogenic pressure which is becoming worrying. Indeed, the continuous exploitation of nearly fifty boreholes has led to a deterioration in water quality and has negatively influenced the hydrodynamic balance of the aquifer. It also resulted in a reduction in spring flows and the appearance of salty wedges, threatening even in the short term and the exploitation of the aquifer and the proper functioning of wetlands (Samraoui and de Belair 1998). In this study, we attempted to use a hydrodynamic and hydrodispersive model: - To assess the condition of water resources, - identify sectors vulnerable to marine intrusion, and - identify the factors responsible for the reduction in flow rates from the main sources and the reduction in the surface area of wetlands in the regionPDFenwater pumping; impacts; southern mediterraneanOther
