The methodology is applied to three series of experiments performed on scale models of basins by Frey et al. (1993), Stovin & Saul (1994) and Dufresne et al. (2009). The comparison of the numerical results with the experimental measurements makes it possible to verify the model's capacity to reproduce the phenomena involved in the sediment transport in the basin on the basis of two data: particle trapping efficiency in the structure and the preferential zones of sediment deposition on the bottom. The three series of experiments present the characteristics that allow applying the model to a wide range of particles and hydraulic configurations. The parameters of the experiments are summarised in Table 1. These experiments correspond to calmed though nonetheless turbulent flows.
