Effects of Bathymetric Complexities and Wind Generation in a Coastal WavePropagation Model

摘要

A new wave modelling strategy has been developed by Holthuijsen et at. (1989) forestimating wave heights for engineering applications in coastal areas. The paper examines two aspects of this model: its ability to adequately predict wave properties in regions with complex bathymetry where diffraction effects are likely to be important, and its ability to model wave growth due to wind. For complex bathymetries, the model is found to give good simulations for sea-states with considerable directional spreading. As the degree of spreading decreased or for certain special wave conditions, model performance was marginal. Finally, the model is used to study the physics of wave decay and wind-induced growth in Saginaw Bay (Michigan) using prototype data. (Copyright (c) 1993 Elsevier Science Publishers B.V.)
