Description :
Digital elevation models and topography profiles of a beach with intertidal bar and through (ridge-and-runnel) morphology in Merlimont, near Somme estuary, were analysed in order to assess patterns of cross-shore and longshore intertidal bar mobility. The beach exhibited a pronounced dual bar-trough system that showed cross-shore stationarity. The bars and throughs were, however, characterized by significant longshore advection of sand under the influence of suspension by waves and transport by strong tide- and wind-driven longshore currents.
