Document type: Conference Proceeding Paper
Part of: Coastal Sediments ’07
Abstract: The paper describes large-scale laboratory experiments performed with simultaneous measurements of suspended sand concentrations, free surface elevations and three-component velocities (including turbulent fluctuations) at several levels above the sea bed. The data from these experiments are used to develop a more correct description of the contribution of vertical velocity to the convective sand flux and the relationships between fluctuations of turbulent kinetic energy and wave energy dissipation for the estimation of local sand suspending and advection to the temporal variation of suspended sediment concentration.
