TO RETREAT IN ORDER TO BETTER FIGHT : LITTORAL PROTECTION OF SHINGLE BEACHES IN THE NORTH OF FRANCE

Bruno Manoha, Charles Teisson

Abstract


Rather than endeavouring to protect a shoreline under severe waves attack, on the northern coast ofFRANCE, a new solution aretreat landwards up to 800 m. With a slight retreat (180 m), the orientation ofthe new shoreline is drawn according to the dominating wave climate and enables the stabilization of the beach. A larger retreat (800 m) could allow the re-estuarisation of a valley. These solutions are tested on a physical movable bed model.
