Title Comparative study of wave parameters derived from spectral and zero-crossing methods
 
Creator Rao, C V K Prasada
 
Description 202-205
Along wave records, collected in deep and shallow waters off Goa, West Coast of India, using ship-borne wave recorder, have been analysed following wave spectrum approach and zero-crossing method (Tucker/Draper method). Comparison of wave parameters obtained from both methods reveals that the significant wave heights (Hs) and zero-crossing periods (Tz) agree resonably well whereas the spectral width parameter (ϵ) and mean crest period (Tc) show some anomalies. Values of ϵ are higher and Tc lower for spectral approach compared to the zero-crossing method. It is envisaged that the use of spectral peak periods in place of Tz or Tc would be more appropriate for wave data sets containing predominant 'sea' and 'swell' components together.
