Three-Dimensional Modeling of Aquifers of the Coastal Basin Gharb, NW Morocco

The Gharb Basin is located in the northwest of Morocco, covering an area of 4000 sq. km. It is especially known for the alluvial style of its deposits and the very heterogeneous character of its aquifers. Moreover, the coastal fringe of its aquifers is uncertain due to the effects of sea level changes during the Plio-Quaternary. To better understand its hydro-geological potential, new technological tools offer new opportunities for visualization and analyzing data acquired by different methods. The exploitation of geo-electrical data in a SIG showed that the sand bodies (electrically resistant) are divided into broad depressions whose limits have been established for the first time (Kénitra-Beht Ouest and Oued Touirza).
