| Abstract | In macrotidal estuaries, tides and the river flow are in constant interaction. The consequent sedimentary structures are varying following different temporal scales. This study focuses on the sediment dynamics of the Charente estuary, located on the French Atlantic coast. The turbidity maximum is reproduced using 3D hydrosedimentary modelling. Several tidal and fluvial forcings are considered. Results show that the tide remains the dominant process at the river mouth. However, the river discharge has a strong influence on the turbidity maximum characteristics (concentration, extension). Cumulated sedimentary fluxes suggest that, in the case of an average river discharge, the estuary tends to import sediments. |
