Abstract: Laboratory measurements of longshore transport are described and it is shown that, for the same wave attack, transport increases with beach slope. Also, the distribution of sediment transport across the beach face is shown to be a function of beach slope and sediment size. A theoretical relationship for cross-shore equilibrium beach slope is presented and the interaction between cross-shore and longshore sediment processes is discussed. Based on radiation stress analysis, theoretical relationships are developed for the estimation of longshore transport as a function of incident wave height and direction, sediment characteristics and beach slope. The predictions of this theory are shown to be in agreement with the experimental measurements.
