The wave incidence and the wave-induced circulation in the surf zone (SZ) isstudied from both experimental and numerical point of view. The DELTA'93experiments were carried out in the Trabucador bar of the Ebro Delta, inthe Spanish mediterranean coast. The emphasis of DELTA'93 was on theSZ vertical flow structure, measuring simultaneously undertow and longshorecurrent in a barred profile. The numerical simulation with NEARGIRQ3D model assumes longshore uniformity and stationarity. The wave decay,2DH currents and 1DV undertow and longshore currents are modelled. Theagreement is quite reasonable as can be seen in the included figures.
