HYBRID WAVE MODEL FOR UNIDIRECTIONAL IRREGULAR WAVES .2. COMPARISON WITH LABORATORY MEASUREMENTS

Numerical predictions of irregular wave elevations and velocities base d on the hybrid wave model are compared with two sets of laboratory me asurements and are also compared with the related predictions by linea r random wave theory and its 'stretching' and 'extrapolation' modifica tions. The satisfactory agreement between the numerical results of the hybrid wave model and the related experimental measurements indicates that the hybrid wave model, especially near steep wave crests, can pr edict irregular wave elevation and velocities more accurately and more reliably than those methods commonly used by the offshore industry.
