【 摘 要 】

A model that predicts the depth variations of wave generated currents within the framework of a 2-D depth-integrated surf-zone model is described. The equations are formulated and solved for the case of a long, straight coast. The model is used to demonstrate that the effects of current refraction are weak and to determine the variation of the 3-D spiral shaped current profiles across the surf-zone. Finally, we show that the mixing coefficient required to get realistic variations of the longshore current is much larger than what the turbulence measurements can justify.
