Abstract

In the present work two numerical models for linear wave propagation, wave induced circulation and sediment transport are presented. The wave model WAVE-L is based on the hyperbolic type mild slope equation and is valid for a compound wave field near coastal structures where the waves are subjected to the combined effects of shoaling, refraction, diffraction, reflection (total and partial) and breaking. Radiation stress components estimated from the hyperbolic wave model drive the depth averaged circulation model COAST for the description of the nearshore currents and sediment transport in the surf and swash zone. The model COAST is coupled with a 3D bed evol
