【 摘 要 】

The wave incidence and the wave-induced circulation in the surf zone (SZ) is studied from both experimental and numerical point of view. The DELTA'93 experiments were carried out in the Trabucador bar of the Ebro Delta, in the Spanish mediterranean coast. The emphasis of DELTA'93 was on the SZ vertical flow structure, measuring simultaneously undertow and longshore current in a barred profile. The numerical simulation with NEARGIR Q3D model assumes longshore uniformity and stationarity. The wave decay, 2DH currents and 1DV undertow and longshore currents are modelled. The agreement is quite reasonable as can be seen in the included figures.
