摘要

To hindcast the wave climate at a particular study area in North-western Coast of Sri Lanka, Wave Transformation Matrix and MIKE 21 Spectral Waves (SW) models were used. Directional wave data recorded at 15m ~ 16m depths in Colombo Port during 1998 – 2015 periods was transformed to the study area by using numerical simulation techniques. Thus, representative nearshore wave climate was established at 20 m water depth in the study area (i.e. Wennappuwa in North-western coast). Transformed wave data was analyzed in both annual and seasonal basis. From our analysis, highest percentage of annual waves at 20 m depth in study area has been identified between 2500N – 2600N directional range. Seasonal wise, southwest monsoon season was recognized as dominant season. Finally, design wave heights for breakwater structures of a proposed harbour were predicted by extreme wave analysis.
