The vulnerability of the Camargue delta to the risk of flooding is experienced differently according to the representations and the practices of the actors. For the public actors in charge of flood risk management and dykes construction and maintenance, flood risk management should mainly be governed through a sectoral, hydrologic approach defined at the scale of the delta.
