A numerical model of the vertical distribution of longshore currents on a plane beach
Abstract A numerical method is developed to calculate longshore currents generated by monochromatic long-crested waves breaking on a plane beach. The method is based on the linearized time-averaged momentum equation in the longshore direction. The equation is solved numerically using a Galerkin method with a series of cosine functions as basis functions. Longshore current profiles across the surf zone at a range of elevations over vertical direction are presented and compared with experimental data. Although the turbulence model used at this stage is only a simple eddy viscosity model, reasonable agreement between computed and experimental results has been achieved.
