Abstract - Modelling the impact of the climatic changes on the dune erosion. The case of the Camargue
Three climatic changes scenariis were investigated by an increase of energy and by the duration of an extreme storm. The wave caracteristics properties and the sea level time series of the referenced storm were increased of about 5, 10 and 20 % in order to define the dune erosion. We evidenced that the wave height displays more influence on the dune erosion than the sea level. Moreover, the storm duration, over 4 days, does not play an important role on the dune erosion. However, there is no proportional relationships between a weak storm energy increase and/or duration, and dune erosion. A small increase of storm will have a large impact on dune erosion in the future. *
