Description 1343-1346
Wave
data during extreme conditions is required for planning structures and shipping
routes. Since the measured wave data is still sparse in the eastern Arabian Sea,
wave information is mainly derived from wave model dataset and satellite derived
data. Hence, it is important to know the performance of these dataset during
high wave conditions. A study is carried out to compare the wave height, period
and direction during high waves obtained from wave model dataset: ERA-Interim
and that measured by the buoy at two locations in the eastern Arabian Sea. One
location is a deep water location and another one is a shallow water location.
The comparison of significant wave height (SWH) between ERA dataset and buoy
data at both the locations shows good correlation (correlation
coefficient=0.85) with root mean square error of 0.87 and 0.53 m. But the
maximum SWH based on ERA dataset in deep water is 15% less than that measured
by the buoy, whereas in shallow water ERA datasets over predicts the maximum
SWH by 9%. The comparison of wave period and direction at both locations shows
significant scattering.
