Rôle des forçages météo-marins dans l'évolution morphosédimentaire récente des cordons littoraux de la rade de Brest

Firstly, the morphosedimentary changes of ten gravel beaches located in the bay of Brest are analysed using aerial photographs taken between 1952 and 2004 and DGPS surveys (2004-2005). Then, an analysis of meteorological and oceanographic conditions during this period is carried out using tide, wind speed and direction data. Finally, the synthesis of these data shows the important role of high water levels and wind conditions in the erosion of this gravel beaches.
