Hurricane Juan generated huge, complex waves in the Northwest Atlantic and coastal waters off Nova Scotia in late Sept. 2003. This study focuses on the accurate, high precision simulation of waves generated by hurricane Juan in coastal waters, applying WAVEWATCHIII (WW3) and SWAN wave models. Cyclone generated waves in coastal water are very complex, compared with those in the offshore and ocean regions. Two issues are addressed which influence accurate, high precision simulations of cyclone- generated waves in coastal waters:
SWAN model's numerical sensitivity during non-stationary simulations in coastal waters;
the incoming two-dimensional wave spectral pattern on model boundaries.
