We hereby compare the performance of a weakly coupled finite-volume model against a fully coupled one on a two-dimensional dam-break test case with movable bed. Both models consider bed-load only and are HLLC based, but the weakly coupled one uses an upwind scheme for the sediment fluxes. It appears that the weakly coupled model is far better at predicting maximum deposition and erosion amplitudes and does not suffer from excessive diffusion regarding bed evolution.
