摘要：
A numerical analysis is performed to predict actual change of beach profile due to cross-shore sediment transport during severe storm. In the existing cross-shore beach erosion studies, calculation of cross-shore sediment transport includes only continuous process of beach erosion but stability of beach slope which predicts time of beach breakdown during erosion is not considered. In this study, the process of cross-shore beach erosion and beach profile change are simulated by various shapes of sand covering over the beach after breakdown. The stability of beach slope using the critical equilibrium analysis is analyzed on every changing beach profile in every given time to predict the actual change of cross-shore beach profile. The measured cross-shore beach profile, storm surge level and wave height in Florida in U.S.A. are used for the numerical analysis and various values of soil modulus based on the existing studies are applied in the stability analysis of beach slope.
