Resumen

Experimental visualizations have been performed of the oscillatory flow and of the sediment motion produced by a sea wave propagating over a rippled bed. In particular the dynamics of the vortex structures generated by flow separation at the ripple crest is investigated along with the mechanism through which sediments are lifted up from the bed and carried in suspension. A numerical model is formulated and the results obtained are successfully compared with the experimental data.
