【 摘 要 】
This study deals with modeling for profile change due to damage progression of rubble mound revetment. The model profiles based on the experimental results consist of three datum points and two sine curves corresponding to the degree of deformation of the revetment. The model profiles agree well with the measured profiles. The model profiles are also used in other experiments and a time-averaged numerical model to examine the change of performance due to damage progression. The reflection coefficient and overtopping rate are taken as performance indices. The measured reflection coefficient decreases slightly, but the overtopping rate increases with damage progression of the revetment. The computed reflection coefficient is almost constant and the overtopping rate shows opposite tendency to the experimental result.
