Abstract

Wave-induced currents in a surf zone must be explained by the change of wave motion. The driving force for nearshore currents is the radiation stresses which are defined as the excess momentum flux due to wave motion. However, there is no model which can describe the three-dimensional structure of the nearshore currents. This study aims to develop a model of this kind, in which only wave motion is taken as the driving force to the currents. Governing equations are derived from the Navier-Stokes equations. This model is proved to reproduce the currents measured in the experiments.
