Modélisation empirique de l'évolution morphologique de la plage du Vougot

Abstract : Understanding shoreline evolution, and in particular, the consequences of shoreline erosion is a major societal concern that threatens to become even more important in the future with the impacts of climate change. Thus it is necessary to improve both knowledge of the dominant physical processes controlling medium to long-term shoreline evolution and morphological evolution models. Here, the interannual evolution of the study site Vougot is analyzed, and an empirical equilibrium model is applied. Once calibrated with observations, the model reproduces well the morphological evolution in the upper and lower intertidal zone. The model then can be used to predict future morphological changes at the study site using wave projections. Current work is focused on integrating the effects of longshore processes, which are relatively important at this site, as well as on integrating the effects of climate change, including improving the approach used to take into account changes in sea levels and the wave climate.
