Hydrogeological Synthesis of Groundwater Resources: Case of the Feija Watershed (South-east of Morocco)
Keywords:Feija watershed, Middle Draa valley, Groundwater resources, Agriculture.
The Feija watershed is located in southeast Morocco. It is the main tributary of the middle Draa valley. It covers an area of 2089.3 km². The Feija watershed dominated by an arid climate. The economic development in the Feija basin is essentially based on agriculture, which requires pumping a considerable amount of groundwater resources. These waters are being overexploited because of the fast growth in the agricultural sector and the influence of adverse climatic conditions. The present study concerns a hydrogeological synthesis of the Feija groundwater, in particular the influence of topographical, climatic, hydrological and geological factors that interact to create a complex system with uncontrolled agricultural consumption. To this effect, and to determine the recharge and discharge rates of the groundwater, the contribution of remote sensing and GIS presents a major role in assessing and monitoring the condition of the groundwater and faced the water stress characteristic of this study area.
