NUMERICAL VALIDATION OF DIRECTIONAL WAVEMAKER THEORY WITH SIDEWALL REFLECTIONS

E.P.D. Mansard, M.D. Miles, R.A. Dalrymple

Abstract


A directional wavemaker theory has been developed by Dalrymple to produce a desired oblique planar wave train at any cross-section in the basin. This theory, which uses the reflections from the sidewalls of the basin, can also account for slowly varying depths. This paper describes a numerical validation of this theory, for the constant depth situation, by a wave diffraction model that was recently verified through an extensive series of experimental investigations.
