Abstract. In this lecture, we will particularly analyze the e ect of the shallowness on
the Navier Stokes equations, together with anisotropic eddy viscosities. We will derive as
an asymptotic model the hydrostatic approximation of the Navier Stokes equations. We
will present a stable mixed 3D-FEM discretization, which allows for the computation of
the 3D-velocity as a whole. Let us emphasize that vertical velocities are not post-processed
