Abstract : Coastal systems should be vulnerable to climate change/variability. The present paper investigates the sensitivity of Truc Vert beach to present day climate conditions as well as possible climate change in the near future. A modeling approach is used, based on three numerical morphodynamic models (MORPHODYN, MARSOUIN, TELEMAC). The first results show an important sensitivity to present day wave classes. Some first indications on the potential influence of wave climate changes are also given, investigating variations of wave classes characteristics. The present work also illustrates the need to go on improving and developing these models.
