| Popis: | A method is described to calculate the relationship (β) between the eddy diffusivity of suspended particles and the eddy viscosity of the fluid. The data were obtained while making suspended sediment concentration measurements near the seabed on the British continental shelf. β was calculated for 0.50 size fractions and varies inversely with the suspended sediment concentration. The values were used successfully to calculate suspended sediment transport rates for separate sand fractions through a spring tidal cycle. Finally, specific values of β are suggested for varying concentrations of sand at a reference height of 100 cm above the seabed. |
