Abstract

A deep-water long-crested breaking wave is generated from a time-stepping numerical model, then replicated in a wave flume. The numerical model is based on the boundary integral method and measurements of the internal kinematics are made during the breaking process with Particle Image Velocimetry (PIV). Velocity measurements are obtained throughout the wave crest, including the plunging spout. After a small shift of the numerical data to match the surface profiles, the predicted and measured kinematics are found to be in good agreement, within the limits of experimental error.
