Coupling of Boussinesq and sediment transport model in a wave flume

摘要

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