REAL-TIME WAVE MEASUREMENTS AND WAVE HINDCASTING IN DEEP WATERS

Deep water waves off Karwar (lat. 14-degrees-45.1'N, long. 73-degrees- 34.8'E) at 75 m water depth pertaining to peak monsoon period have bee n measured using a Datawell waverider buoy. Measured wave data show th at 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 duri ng the study period. Spectral analysis shows that measured deep water waves generally formed single-peaked spectra conforming to the sea gen erated 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.
