| Summary: | Numerical models are established to study the wave dynamics and circulation in Potter Cove and their interactions with the surrounding environments. Wave propagation from deep ocean to coastal waters was simulated using the SWAN wave model. And tidal propagation was studied using the unstructured-grid FVCOM model followed by a tidal analysis. FVCOM simulations with different tidal, wind and wave forcings were implemented to assess the relative importance of the forcings on the flow patterns in the cove. The model results were compared with the NDBC buoy data, WAVEWATCH III model results and satellite data. While tides have minimal influence on the circulation in Potter Cove, wind plays a significant role in the circulation patterns which are highly dependent on the wind speed and direction. Bed shear stresses were calculated to provide an insight on the bed sediment erosion characteristics in Potter Cove. The local residence and flushing times were also estimated. |
