The contribution of geophysics and hydrogeology in the knowledge of the Eastern Haouz aquifer (Morocco)

Abstract

Eastern Haouz is an intra-mountain basin characterized by a semi-arid climate. This area experiments an increasing demand for drinking water and agricultural productivity water. To satisfy this demand, local villages of the area solicit the surface water (rivers and springs) and groundwater reserves. Piezometric map (Fig.1) shows that groundwater recharge is driven by anastomosis in contact with limestone outcropping in the High Atlas Mountains and shales exposed in the Jebilet mountains, as well as infiltration of irrigation water (S. Rochdane 2013). Maps of hydrographic network and piezometry show the overlap between the groundwater divided line and surface water divided line.
