This Coastal and Hydraulic Engineering Technical Note (CHETN) summarizes the state of understanding of the influence of grain size on surf zone sediment transport and is a companion to Smith et al. (2004). This CHETN discusses details of bed-load and suspended load transport, and the classical bed-load regime is shown to encompass two distinct modes of transport. Four LST models with varying le...

The GENESIS model has proven its capabilities in numerous projects worldwide for simulating shoreline change and longshore sediment transport on wave-dominated beaches. Even though the model has been made generally applicable to “almost arbitrary” configurations of shoreline shapes and structural measures, some important features are not yet represented. This paper describes a new major capabil...

In this paper, a hydraulic model experiment was conducted to investigate the mechanism of longshore sediment transport on sloping beach 1:7 using circular wave tank equipped with spiral maker. The experimental results revealed that cross-shore predominant up formation equilibrium cross-section. Then actively dominant near bar after development topography. wave-breaking positions and characteris...
