Sediment budget in the southern inlet of the Gironde Estuary (SW France)

The southern inlet of the Gironde estuary is a secondary sedimentary entity separated from the main channel by an emerging shoal. This sandy coastal system evolves under the influence of strong tidal currents and high energy atlantic swells. Severe erosion occurs along its coastline and important sediment displacements were observed on a long-term scale. Two main processes are involved in the sediment budget of this system: longshore drift and sediment loss to the open sea
