Abstract

A fiilly nonlinear 2-dimensional numerical wave flume, based on the boundary integral equation method, has been developed. Waves are generated by a hinged paddle wave maker at one end of the flume and a sponge type wave absorber at the other end. A fourth order Taylor expansion technique is used for the time stepping of the free surface. Simple monochromatic waves have been generated and very good agreements are found when compared with Stokes wave profiles. The wave flume is used to study deep water wave breaking due to large periodic displacements of the wave paddle. Wave breaking as a result of energy focusing a group of waves of different frequencies and heights, is also studied. For each br
