Sediment transport particular events and beach profile response

Abstract : A field campaign was carried out as part of the ECORS project on the macro-tidal beach of Truc Vert (France, March-April 2008). Velocities, sediment concentrations and bed evolutins recorded at the mid intertidal zone are presented, covering calm (Hs~0.5m)and energetic (Hs~1m) conditions. Cross-shore transport rates were estimated using the BAILARD (1981) model for the total load transport, beach profile changes for the net transport and suspended sediment fluxes. Under energetic wave forcing the undertow was large and sediment transport was directed offshore whereas under calm conditions the undertow was weaker and sediment transport was directed onshore.
