Santoro, A., Guedes Soares, C. and Arena, F. (2013), “Analysis of experimental results on the Space-time evolution of wave groups in crossing seas”, Proceedings of the ASME 201332nd International Conference on Ocean, offshore and Arctic Engineering (OMAE2013), June 9-14, Nantes, France, pp. 11533

The space-time evolution of high wave groups in crossing seas is studied. Profiles are calculated by applying Quasideterminism theory of Boccotti to laboratory data, given that a high crest takes place in a fixed point in the basin. It is observed that the high waves group is given by the superposition of two wave groups, associated one to the low-frequency component of the frequency spectrum and the other to the high-frequency one. It is shown how in crossing seas, the change in direction of one system affects the evolution of the related group, without any influence on the evolution of the other one. Different locations of high crest occurrence have been considered in order to study the effect of the change in spectrum on the deterministic profiles. It is shown that in crossing seas the profile at each location reflects the spectrum related to that specific point.
