| In marine coastal environments, storms have a major morphological impact on sand beaches. This study, part of the French Programme National d'Environnement Cotier, consisted in developing and applying hydrodynamic and sedimentary models to simulate the major processes that modify sand beaches. In order to study sediment dynamics, we developed three models to simulate waves, currents and sediment transport associated with a storm event. The wave model was a Mild Slope Equation model based on the parabolic approximation of the refraction-diffraction equation of Berkhoff. The hydrodynamic model was obtained by the depth-average of Navier Stockes' equations forced by the terms of radiation stresses induced by waves. The sedimentary model SEDSIM developed by... |
