Abstract: Most studies that use numerical models for wave-resolved morphodynamics in the swash zone, use depthaveraged models. These models typically represent system variables such as flow velocities and sediment concentrations in a depth-averaged or depth-integrated way. Such models then either assume a uniform vertical profile, or some other pre-determined vertical profile shape. Previous research using such models has shown that they can reproduce the depth-averaged hydrodynamics very well. However, in terms of sediment transport and morphodynamics, these models often have difficulty reproducing the sediment transport and morphodynamics (e. g. Mancini et al., 2021; Ruffini et al., 2020). In order to investigate the importance of the aforementioned vertical structures, we have developed a depthresolving CFD (computational fluid dynamics) model suitable for modelling sediment transport and morphodynamics in the swash zone. The model uses the Reynolds Averaged Navier-Stokes (RANS) equations and a Volume of Fluid approach and
