Abstract
The numerical study of flow in the coastal zones of Cameroon estuary has retained the attention in this research. The soils of this zone are porous. The study has taken in account the Richards model to describe the fluid flow in these porous areas. Researchers have associated to this model that of Brooks and Corey, so as to determine the hydrodynamic parameters for the different types of soils studied. Researchers have resolved Richards equation which is strongly non-linear by taking into account Boussinesqs approximations. Knowledge of initial conditions and the definition of convergence conditions linked to the time scale are indispensable to obtain the objectives. The results obtained define the hydraulic and the hydrodynamic characteristics of soils at the estuaries cost of Cameroon, putting in evidence the parabolic character of the model studied and the presence of capillarity forces in such areas. The curves obtained have permitted to realize the pertinence of these results. It comes out that the pressure gradient and the soil texture of the area studied are indispensable elements in the study of drainage and the infiltration of fluids in porous areas.
