Abstract

Longshore sediment transport usually determines the dredging requirements of harbours, navigation channels and tidal inlets, and needs to be quantified for the design of, for example, beach nourishment. An accurate longshore transport model was developed and is described below. An overview is given of the comprehensive studies on which this model is based. The model is robust and well verified. The layout, input data, output and computer requirements of the model are discussed. Different applications are presented showing how the results of this model are used: for the design of groynes, breakwaters and sand bypassing systems at ports, and to complement three-dimensional computational morphological models. The model provides, per wave condition, the cross-shore distributions of the wave height, mean water levels and the longshore transport. In addition, the longshore transport climate at the particular site is summarised, and weighted, mean longshore transport distributions for both upcoast and downcoast transports are supplied.
