【 摘 要 】

The present paper describes a numerical study of infragravity waves forced by obliquely-incident wave groups. In this study, the depthintegrated, shortwave-averaged nearshore circulation model SHORECIRC (Van Dongeren et al., 1994), which includes the quasi three-dimensional effects, is used. The governing equations that form the basis of the model, as well as the numerical model and the boundary conditions are described. The model is applied to the case of leaky infragravity waves. The magnitude of the quasi 3-D terms and their effect on the infragravity wave envelope is analyzed, and the velocity profiles of the infragravity waves are shown.
