Sediment transport by combined waves and currents - contract completion report

This report summarises the results of the development of improved methods for predicting sand transport in the coastal zone performed under MAFF Contract No.CSA1435. A new sediment transport formula for combined wave and current conditions has been derived, incorporating results from linked work at University College North Wales. The formula has been successfully tested against field data. A numerical model to predict wave and current distributions, sediment transport, and bed morphology changes on gently varying coastlines has been developed, and successfully tested against laboratory wave flume data.
