Abstract

The waves along the east coast of India during south-west monsoon have great importance due to the prevailing rough conditions. Significant Wave height (Hs) and other wave conditions are measured at a location of 20m water depth off east coast of India during south-west monsoon 2009. Wind-sea (Hsw) and swell (Hss) components are separated from the measured data, to look into the characteristics of the waves at the measured location. It is observed that the sea-state is dominated by swells arriving from south-east (SE) to south (S). The maximum measured Hs is 2.62 m. Good positive correlation of 0.84 is observed between Hss and Hs. The contribution of Hss to Hs is 63.2 and remaining is due to Hsw. Wave age shows the presence of young sea with significant occurrence of swell. The spectral band width parameter (e), calculated from the measured data indicates that the wave components cover wide range of frequencies. The high values of spectral narrowness parameter (v) and peakedness parameter (Qp) are observed during the study period.
