| Abstract: | Understanding wave patterns in the Bay of Bengal is crucial due to the increasing intensity of tropical storms caused by climate change and rising sea levels, which pose significant risks to the coastal areas of Bangladesh. Additionally, the channel at the sea near the Port of Payra has been deepened to boost Bangladesh’ international trades. Therefor, an analysis of the significant wave height and wave directions along the coast and offshore of Bangladesh can provide the impact of cyclones and changes of wave characteristics caused by the channel. The first part of this research focuses on investigating the significant wave heights and wave directions using three datasets: buoy measurements, the WaveWatch III (WW3) model, and the SWAN model. The buoy data provides real-time observations of wave conditions, while the WW3 and SWAN models offer numerical simulations based on wind data. This analysis provides the significant wave heights of different locations and the corresponding wave directions, showing the impact of seasonal variations and cyclonic storm events on the wave patterns. In the second part, the three datasets are compared to evaluate their accuracy and reliability. The analysis concluded that the significant wave height of the buoy measurements decreases as the waves propagate towards the coast, while the wave direction remains aligned with the channel. The WW3 model provides wave data for a point further offshore than KP60, showing significant wave height values slightly higher than KP60. The SWAN model also shows slightly higher values at the WW3 point. The wave directions align with the buoy measurement data, corresponding to the channel direction and refract when the channel direction slightly shifts. |
