IRREGULAR WAVE TRANSFORMATION OVER DEFORMING SUBMERGED BREAKWATER

摘要

A numerical model based on time-averaged continuity, momentum and energy equations is applied to irregular wave transformation over a deforming submerged breakwater. Experiments were also conducted to investigate the accuracy of the numerical model and the relation between the function of a wide submerged breakwater and its deformation caused by wave attack. The numerical model predicts the measured cross-shore variations of the mean and standard deviation of the free surface elevation and horizontal velocity well. The results of the experiments show that the considerable deformation of the submerged breakwater has little influence on wave transmission and reflection.
