Resumen
This paper presents a numerical investigation of sediment transport under the combined effect of waves and current motion. Comparison of predictions to experimental measurements showed good agreement. The presence of a second peak over the decelerating and flow reversal was predicted by the numerical model due to the inclusion of an extended bed reference concentration and a turbulence model that is able to predict a sudden increase of the turbulent properties of the flow over this stage. Evidence suggests that the second peak is caused by an inflection point in the velocity profile leading to high diffusivities near the wall.
