Resumen
Forcing of the nearshore circulation system by incident wave groups is examined. Attention is focused on the generation of migrating rip currents and development of low frequency motion. Analysis of experimental results categorises the migrating rip currents as very low frequency motion in the FIG energy band. It is suggested that migrating rip currents, in addition to shear waves, are a valid generation mechanism for very low frequency motion in the nearshore region.
