Abstract
The area of the plateau of phosphates, and the plain of Tadla which extends over an area of 12300 km2 in Morocco central, is very well known for its interests industrial, economic and social very important. The groundwater resources in waters that is more vulnerable to overexploitation and/or to the alteration. The aquifer system is present in the coverage meso-Cenozoic and quaternary which has deposited on the Paleozoic formations. The modeling of the hydrodynamic functioning of this multilayered system allows the understanding and monitoring of the hydrogeological balance sheets, it is in the heart of the management of resources and their preservation. This work aims at the finite difference modeling the multi-layered complex of the plateau of phosphates and the plain of Tadla, the application adopted for the realization of the modeling is the GMS (Groundwater Modeling System of Aquaveo) with the Modflow code (U.S. Geological Survey) which have proved flexible enough for the design and the manipulation of the modeling. The conceptual model is composed of 4 bunk aquifers. The rivers of Oum Errabia, Derna, Laabid and Tassawout rivers form the main drains in the model, as-the climate inputs combined with the surplus water after irrigation of the perimeters of Tadla, without evaluated by the model of the hydrological balance "Wetspass" and form the main resource of the recharging.

Abstract: (french)
Le domaine du plateau des phosphates et la plaine de Tadla qui s'étend sur une superficie de 12300 Km2 au Maroc central, est très connu pour ses intérêts industriel, économique et social très importants. Les ressources souterraines qui s'y trouvent sont de plus en plus vulnérables à la surexploitation et/ou à l'altération. Le système aquifère est présent dans la couverture méso-cénozoïque et quaternaire qui s'est déposée sur les formations paléozoïques.
La modélisation du fonctionnement hydrodynamique de ce système multicouche permet la compréhension et le suivi des bilans hydrogéologiques, elle est dans le cœur de la gestion des ressources et de leur préservation.
Ce travail vise la modélisation en différences finis du complexe multicouche du plateau des phosphates et la plaine de Tadla, l'application adoptée pour la réalisation de la modélisation est le GMS (Groundwater Modeling System d'Aquaveo) avec le code Modflow (de l'U.S. Geological Survey) qui se sont avérés assez souple pour la conception et la manipulation de la modélisation. Le modèle conceptuel est composé de 4 aquifères superposés. Les rivières d'Oum Errabia, Derna, Laabid et Tassawout forment les principaux drains dans le modèle, quant-aux apports climatiques conjugués aux surplus d'eau issue de l'irrigation des périmètres de Tadla, sans évalué par le modèle du bilan hydrologique « Wetspass » et forment la principale ressource de la recharge. A partir des résultats du calage du modèle du système aquifères «en entier » on peut remarquer sa flexibilité pour reproduire le fonctionnement hydrique d'un système complexe et multicouche.
