Wave groupiness factors defined by wavelet transform

  • Received Date: 2009-04-29
  • Rev Recd Date: 2010-03-10
  • Two new factors based on the wave energy process deduced by wavelet transform are proposed to describe the groupiness degree of waves. Through numerical wave results and field data, their effectiveness is confirmed by the comparaison with the commonly used wave groupiness parameters, therefore the ability of wavelet transform to analyze wave groupiness in the time-frequency domain is demonstrated. And the infulence of the wave record length on the variation of the groupiness factors is discussed in detail. The analyzed results indicate that the wave record length has great influence on the wave groupiness parameters, and it is suggested that, for the simulation and analysis of waves regard to wave groupiness, at least 400 to 500 waves should be simulated.
