The original feature of the computation lies in the unknowns of the momentum equations: Usually in the shallow water equations the unknowns are the velocity and the water depth (or the free-surface elevation). Here, the water depth is assumed to be known: h follows the local open sea level subject to tide, and varies with respect to time, but is taken uniform in the lagoon, as propagation time is negligible on such a short distance. In conclusion, it is found that nearly 5% of the water in the lagoon is renewed during 1 tide with wind, so that the retention time of water is only 10 days. It would have been 13 days without wind.

The effect of friction on both hydrodynamics and sediment transport has been illustrated in this complex environment. Different values of the Strickler coefficients, ranging from flat bed to dune regimes, have been compared in order to reproduce both the free surface elevation and mean flow velocity measurements. For sand transport rate predictions, Van Rijn's (2007) formulation has also been implemented in order to predict the rippled bed roughness.

Dealing with dry zones is now common practice but hinders a lot classical advection schemes. We present here a new class of advection schemes combining the best properties of implicit finite element and explicit finite volume schemes. The resulting capabilities of the method are: mass-conservation (water and tracers), be it in 2D or 3D, monotonicity (depth and tracers), along with very large time steps, as there is no CFL condition, even with tidal flats, which was the main goal. The technique works in parallel and can also be used to gain flexibility in building highly distorted 3D meshes between bottom and free surface. It can also be used to solve the Exner equation for bed load transport. Test cases are presented.
