Abstract


This paper describes the details of a 2D model of. waves and undertow in the surf zone. The model uses an assumed shape of the undertow velocity profile together with the wave energy equation, surface and near-bed shear stresses and the mass flux balance due to the wave drift, surface roller and undertow velocity to compute the cross-shore wave development, surface set-up/set-down and the vertical distribution ofthe undertow velocity at cross-shore sections. The numerical model has been tested against both laboratory and field data and produces good agreements.
