The aim of this paper is to present the results of sediment transport measurements, coastal hydrodynamics and beach morphological surveys carried out on 3 sandy barred macrotidal beaches of Northern France (Zuydcoote, Wissant, Hardelot). Using sand trapping, the AA. examine the possible role played by intertidal bar and through morphology on longshore and onshore-directed sand transport. Results show that intertidal bars are responsible for significant wave energy dissipation leading to a decrease of sand transport towards the upper beach. Sediment transport appeared to be substantially higher on the bars than within the troughs due to wave breaking processes that are responsible for intense sand remobilization. The comparison of onshore sediment transport with longshore transport showed that onshore-directed transport is generally higher than the longshore sediment flux
