The paper presents a numerical investigation on alongshore surf and swash currents. The study has been carried out in the framcwork of wave-resolving Boussinesq-type models. Two moving shoreline treatment techniques, namely slotted-beach and wetting-drying methods introduced for this class of models have been implemented into an enhanced version of FUNWAVE2D. Both methods are compared in the simulation of longshore currents with simple, realistic bathymetry. The numerical model, tested under the SandyDuck field conditions, has produced fairly good results. An insight into the capability of the model to predict the alongshore drift velocity of the water mass in the swash zone is also given.
