Mesh Generation

Modifying the mesh boundary arc properties. Trial runs shown a significant change in the result. The change has provided a comparable result with shortfalls in some places.

Mesh refined by including individual polygons between0-20m depth;20-50m depth;50-100m depth and 100-offshore. result doesn’t have much change after refinement.

Mesh analysis helped in reducing simulation time.Different Wind datasets,

ECMWF Wind data-0.75x0.75 deg resolution ECMWF Wave data-0.75x0.75 deg resolution NCEP Wind data-0.205x0.205 deg resolution

Sensitivity Analysis:Sensitivity analysis carried out with open source wind data(6hourly and hourly) and constant wave climate as boundary condition, it was observed that model results have no much variations. Changing input wave climate data with higher spatial resolution gave better results and temporal resolution such as hourly data may give higher correlation.
