MEASURED AND PREDICTED SUSPENDED SAND TRANSPORT ON A SANDY SHOREFACE

摘要

This paper describes on site field measurements of sand transport with two different types of instruments at 13 m water depth at a location 2 km off the coast of Noordwijk aan Zee, The Netherlands. The measurements are compared with results from four practical model combinations using different predictors for the combined current and wave-related shear stress, the reference concentration and the wave boundary layer thickness. Measurements are also compared with results from the Bailard (1981) suspended load sand transport model. Best overall predictions of the measured suspended transport rates are made with the Bailard model.
