SEDIMENT TRANSPORT AROUND A MOUND BREAKWATER: THE TOE EROSION PROBLEM

Asuncion Baquerizo, Miguel A. Losada

Abstract


The combined action of waves (incident and reflected) and the along breakwater current driven by wave energy dissipation inside an infinitely long porous breakwater under oblique wave attack (Baquerizo and Losada, 1998), is taken into account to study the formation of bars in front of the structure and the sediment transport at the toe of it. The main features of the bars are explained in terms of the incident wave characteristics, remarking the wave incidence angle dependence, and the structural and hydrodynamic properties of the breakwater. Results may explain the existence of erosion/deposition patterns at the toe of the structure.
