Large Scale Evolution of the Littoral of the Rhone Delta (Southeast France)

Serge Suanez, Mireille Provansal

Abstract


A study of changes to the Rhone delta littoral at the mouth of the Rhone delta was made using diachronic analysis of aerial photographs and satellite images. The evolution of the coastline shows that the littoral has been prograding over the last fifty years. The evolution by different sectors shows that the sectors located to the east of the mouth of the Rhone have prograded while the western part has eroded. The whole of the littoral is being displaced towards the east because of the action of littoral drift currents, oriented west-east, and the western waves.
