The study of the natural constraints in the basin of the Gharb is based on the integration and the numeric analysis of the multisources data and a classical synthetical approach. The zone is a dissymmetric basin, limited by two great structural domains: Mesetan domain to the Sourth and Rifian domain to the North. It results from this configuration a flat zone with not very deep stream beds. The climate is of Mediterranean type. From a sismotectonical, the study zone is nather quiet central part corresponds to asismical or low sismical domains.
The morphology, the pollution of water and soils, the vegetation and the exploitation of the quanies are the main constraints questioning the management of the basin of the Ghrab. The integration of the whole multisources data in a SIG, seems the more efficient method in term of the time and for the management of the spatially referenced data.
