摘要：

Cross-shore sediment transport rates in the nearshore zone are estimated by the numerical model of sheet flow sediment transport of Katori et al. (1996). After showing the sensitivity of sediment transport rate to the shape of bottom velocity profile, cross-shore distributions of sediment transport rate in the nearshore zone are calculated using estimated near-bottom orbital velocities and corresponding undertow velocities. Calculations explain most of the results of recent laboratory and field studies. The same kind of criterion presented by Sunamura and Horikawa (1974) to separate accretional and erosional profiles is obtained.
