Abstract
Boussinesq type equation has been coupled with sediment transport model to simulate sediment transport in a wave flume. A new eddy viscosity model has been applied to calculate wave decay as well as suspended sediment concentration. A bed load transport formula based on an energetic transport of Bagnold-type model combined with suspended load model was validated under the condition of a spilling wave. The applicability of both eB and cf has been investigated. The result indicated that two sets of parameters cf = 0.017 with eB = 0.21 and cf = 0.003 with eB = 1.03 calculated a similar bed level change. Comparison of calculated and measured bed level change is fairly good in offshore and near breaking point. However, the model cannot predict accretion in swash zone.
