The longshore transport along a sandy beach resulting from the combination of a longshore current and waves is computed. This computational procedure is based on the principle that because of the waves the bed shear of the current is increased. The bed load can be computed with any bed load formula (the formula of Frijlink which is commonly used at the Delft Hydraulics Laboratory is used in the paper), taking into account the previously mentioned effects of the waves. The transport in suspension is computed according to the procedure suggested by Einsgein. The influence of the assumed thickness of the layer in which the bed load is considered to take place and which determines the concentration of suspended material at the bed is presented. The results of measurements in a laboratory basin and along the coast of Queensland (Australia), are presented.
