Note générale :	The paper presents flow mechanisms in large sedimentary bassins with a distinction between the behaviour of aquifers and aquitards. Taking advantage of this difference, a discretisation method is presented, with nesting square meshes of variable size in quasi three dimensions. A finite-differences technique gives a method for solving the flow equations on this discretised flow domain. An application of the method in the northern sahara is presented, with special emphasis on the use of the model to optimise the exploitation of groundwater resources. Also problems of mass transport in such systems are outlined (résumé de l'auteur).
