Abstract: The paper applies the wind-field data on Super Typhoon Saomai and spectral model to simulate the wave field of typhoon in offshore water.The wave refraction,bottom loss and wave breaking are taken into account in the model.The parameters of waves inside the Shacheng harbour are computed by the use of Boussinesq equation,in which the shallow-water deformation,diffraction,refraction,reflection,seabed friction of waves and nonlinear interaction between waves are taken into account.The distribution characteristics of waves in the Shacheng harbour and the causes of disaster are analyzed,when the Super Typhoon Saomai makes landfall in the harbor directly.
