Abstract:

Kinematics of transient wave overtopping on coastal breakwaters has been studied both experimentally and numerically. For the laboratory experiments, solitary waves with moderate wave amplitude are used as the incident waves. The wave profiles are obtained by resistance type wave gauge. The two dimensional water particle velocities are measured by a portable, four-beam, fiber optic Laser Doppler Velocimeter (LDV) system. For the numerical analysis, potential flow theory and Boundary Element Method (BEM) are used for analyzing the wave field induced by the coastal structure. It is found that the numerical results compared well with the experimental data in the case where the numerical model is valid. Some interesting experimental observations are also presented.
