EXPERIMENTAL INVESTIGATION OF NONLINEAR WAVE INTERACTIONS, WAVE TURBULENCE AND ROGUE WAVES

The aims of this project are to study the wave dynamics, formation mechanisms and statistical properties of extreme and rogue waves on the water surface. Bimodal/crossing seas can generate extreme and rogue wave events and are relatively common in the open ocean. A series of experiments was carried out in the Marintek Ocean Basin in Trondheim under conditions close to those found in the open sea. Rogue waves, i.e. events with crests larger than or equal to five times the standard deviation or wave heights larger than or equal to twice the significant wave height, were observed in each test. The mean height of the highest waves increased with increasing record length and increasing kurtosis. For the bimodal/crossing conditions there was little difference between the observed values of kurtosis and an empirical estimate, particularly if the effect of bound waves are included.
