In the present study, the three-dimensional, turbulent, free-surface flow, developing by the oblique propagation of breaking waves over a constant slope bed is numerically simulated. Then, two-dimensional simulations of suspended sediment transport, induced by normal to the shore wave breaking over the same beach, are performed. The main objective is to investigate in depth the flow structure in the surf zone, as well as the behavior of sediment suspension. Predicted profiles of the undertow and the longshore current at several positions in the surf zone, are presented. For the sediment transport simulations, cases of sediments of various grain sizes are investigated. During wave breaking and also in the surf zone, strong uplift of bed sediment is observed.
