Influences relatives des agents hydrodynamiques sur la mobilité sédimentaire des Pertuis Charentais Cas des sédiments non-cohésifs = Relative influences of hydrodynamic factors on the sediment mobility of the pertuis charentais (France). A non cohesive sediments study

Abstract

This paper investigates the relative influence of waves, wind-induced current and tidal current on the sediment mobility of a macrotidal environment belonging to the inner shelf seaward of the pertuis charentais (France). Past studies, based on hydrodynamic measurements already showed the dominant role of swells in the initiation of the motion of sand in an area located between the Ré and Oléron islands. Even if the method has some limits, using wave (SWAN) and 2DH hydrodynamic (MARS) modelling, we extend spatially the knowledge of the relative contribution of waves (without consideration of wave-induced currents), tides and wind-induced current in the non-cohesive sediment mobility.
