Recherche d’indicateurs géomorphologiques de variation de l’orientation des houles sur les côtes françaises de l’Atlantique et de la Manche au cours des 25 dernières années, analyse des données et comparaison avec les données de l’atlas numérique de houle EDF-LNHE

Abstract

Long-term evolutions of wave orientation are important parameters that explain shoreline evolutions and coastal risks. Within the DISCOBOLE project (Donnees pour le dImensionnement des Structures Cotieres et des Ouvrages de BOrd de mer a Longue Echeance), the lack of record of this parameter along the Channel and Atlantic French coasts requires to identify geomorphological features (geomorphological indicators) that indicate wave orientations and evolutions during the last decades. Within this aim, the evolutions of the axis of trailing spits, tombolos and cuspate beaches and beach rotations are analysed over the last decades by mean of present and old aerial photographs and maps. Alterning periods of meridian and zonal orientations are then identify. From 1979 to 2003, results are compared to the data obtained in the EDF-LNHE numerical atlas of waves.
