Real time wave measurements and wave hindcasting in deep waters

Abstract

Deep water waves off Karwar (lat. 14~'45.1'N, long. 73~'34.8'E) at 75 m water depth pertaining to peak monsoon period have been measured using a Datawell waverider buoy. Measured wave data show that the significant wave height (Hs) predominantly persisted between 2.5 and 3.5 m and the zero-crossing wave period between 6 and 8 sec during the study period. Spectral analysis shows that measured deep water waves generally formed single-peaked spectra conforming to the sea generated by local wind which is predominant in the monsoon period (June, July). The results obtained from the wave hindcast model seem to show a good agreement with those from the measured data with a correlation coefficient of 0.93 between computed and measured Hs values
