Wave characteristics off Goa for the period, November to May

Abstract

Waves were recorded off Calangute, Goa, India, from November, 1973 to May, 1974. The records were analysed for various wave parameters, and their distributions were studied. For the particular period of observation, the significant wave height was found to be low (maximum 75 cm). About 90% of the wave periods (zero-crossing periods) ranged between 5 sec and 8 sec. The spectral-width parameter values concentrated within 0.55 and 0.80. The energy spectrum and the period distribution correspond to the low-velocity wind system present in the Arabian Sea during the season
