The dynamics of wave-forced flows near the shoreline is illustrated and discussed, with specific focus on the influence that frictional Chezy contributions have on the shoreline motion itself [1]. An asymptotic analysis, valid for vanishing water depths, reveals that the use of such a term leads to a non-receding motion of the shoreline. This phenomenon is induced by a thin layer of water which, because of frictional forces, remains on the beach and keeps it wet seaward of the largest run-up. However, the dynamical influence of such a frictional layer of water on the global wave motion is very weak and practically negligible for most of the swash zone flow. The presence of a non-receding shoreline has called to some clarifications on the role of some ad-hoc tools used in numerical models for the prediction of the wet/dry interface.
