• Evaluation of a Cross-shore Outflow Rate of Suspended Sediment

抄録

A cross-shore outflow rate of suspended sediment is important in estimating coastal sediment budget. On estimating an outflow rate, vertical distributions of concentration of suspended load were evaluated as a function of bottom friction velocity due to wave action and settling velocity of suspended load. With these results, by solving numerically the conservation equation of sediment and the advective diffusion equation of the suspended load, and integrating it in the cross shore direction from the location of a berm to that of the critical depth for drift sand movement, a sediment loss flowing to a deeper region than the critical depth for drift sand movement was obtained. As a result, the bottom changes due to suspended load cannot be neglected.
