Communications on Hydraulic and Geotechnical Engineering: Sediment Concentrationand Sediment Transport Due to Action of Waves and a Current

摘要

The ultimate objective of the study is to investigate the mechanism of the cross-shore transport phenomenon to improve existing predictive models. In the study, emphasis is placed on two main areas: the spatial and temporal behavior of sediment concentration (on an intra-wave scale) under waves with a current; and the relative importance of the fluctuations of sediment concentration and velocity in sediment transport. To achieve this objective, laboratory experiments were carried out in a wave flume. Local instantaneous sediment concentration and velocity were measured under the combined action of non-breaking waves and a current.
