Cherneva, Z. e Guedes Soares, C. (2011), “Non-Gaussian Wave Groups Generated in an Offshore Wave Basin and their Statistics”, Proceedings of the 30th International Conference on Ocean, Offshore and Arctic Engineering (OMAE 2011), 19-24 June, Rotterdam, The Netherlands, ASME, New York, USA, paper: OMAE2011-50317

The main goal of this work is to investigate the wave groups using data from a deep water basin. Available data are for unidirectional waves measured at several fixed points situated in different distances from the wave maker. Previous works of many authors show that such series describe a process which differs significantly from the Gaussian one. Omitting the usual envelope definition by the Hilbert transform an upper and lower envelopes are introduced. Then the mean high run, mean group length and their distributions are found and compared with the theoretical results for Gaussian process. PDF documents: 1.3.101 - OMAE (2011).pdf
