Measurements of Shallow Water Breaking Wave Rollers
Large scale laboratory experiments concerning breaking wave propagation over a fixed-bed, barred beach were performed. The primary observations of interest were video intensity time series obtained from a set of high-resolution video cameras in order to study the onset of wave breaking in shallow water and wave roller transformation in the surf zone. The approach is new in the sense that the an...
متن کاملEmergence of coherent wave groups in deep-water random sea.
Extreme surface waves in a deep-water long-crested sea are often interpreted as a manifestation in the real world of the so-called breathing solitons of the focusing nonlinear Schrödinger equation. While the spontaneous emergence of such coherent structures from nonlinear wave dynamics was demonstrated to take place in fiber-optics systems, the same point remains far more controversial in the h...
متن کاملA Comparison of Drogue and GEK Measurements in Deep Water
Two series of current measurements made with GEK and drogues arc shown to agree closely, not only in the averaged results of three days’ data, but in short-period variations about the mean. The variations measured are probably too large to bc the ordinary tide, and the possibility of their being the orbital velocities of internal waves is discussed.
متن کاملSimulation of static sinusoidal wave in deep water environment with complex boundary conditions using proposed SPH method
The study of wave and its propagation on the water surface is among significant phenomena in designing quay, marine and water structures. Therefore, in order to design structures which are exposed to direct wave forces, it is necessary to study and simulate water surface height and the wave forces on the structures body in different boundary conditions. In this study, the propagation of static ...
متن کاملExperimental evidence of stable wave patterns on deep water
Recent predictions from competing theoretical models have disagreed about the stability/instability of bi-periodic patterns of surface waves on deep water. We present laboratory experiments to address this controversy. Growth rates of modulational perturbations are compared to predictions from: (i) inviscid coupled nonlinear Schrödinger (NLS) equations, according to which the patterns are unsta...
