ENTRAINMENT AND TRANSPORT OF FINE SAND BY COMBINED WAVES AND CURRENT: AN EXPERIMENTAL STUDY. (1992). Coastal Engineering Proceedings, 1(23). https://doi.org/10.9753/icce.v23.%p
Resumen
Experiments have been performed in a large wave flume in order to measure sediment transport rate of fine sand under combined regular waves and current. Instantaneous velocities and concentrations are measured using ultrasonic velocimeters and optical turbidity probes. Suspended transport rates, as obtained from vertical integration of measured fluxes, are decomposed into a mean current and an oscillatory wave components. Under waves only, the wave contribution is in the direction of wave propagation. Under combined waves and current, the wave contribution is found to systematically oppose the direction of superimposed mean current.
