| Abstract: | In this paper, flume experiments are focused on sediment transport inside and outside the surf zone. According to the energy
dissipation balance principle of sediment-laden flow and the similarity between energy dissipation of spilling breaking wave
and hydraulic jump, formulas are proposed to predict time averaged suspended sediment concentration under both non-breaking
and breaking waves. Assuming that the sediment diffusion coefficient, which is related with energy dissipation, is proportional
to water depth, formulas are proposed to predict close-to-bed suspended sediment concentration and vertical distribution of
suspended sediment under spilling breaking waves, and the prediction shows a good agreement with the measurement. |
