Vulnerability to climatic changes on Mediterranean beaches: a modelling approach
Résumé
These models were used in the framework of a simulated meteorological cycle describing the seasonal evolution of hydrodynamic factors. Results from monthly 2DH evolution simulations show a perfect fit with field data obtained on the beaches in Sète (Certain, 2002). Morpho-hydrodynamic feedback of a bar having undergone reinforcing is also examined. All these assumptions should, of course, be systematically checked, the purpose of the exercise being to assess, through mid-term bathymetric evolution simulation. Then, vulnerability can be studied: the vulnerability of coast/beach will be defined and studied based on in-situ observations and model results will be taken into account as a modulator of the physical vulnerability.
