Migration of offshore mound constructed by dredged materials
A numerical model to predict the migration rate of submerged mound constructed by dredged materials due to waves is developed in this paper. The model is based on Bailard's sediment transport rate formula, Stokes' second-order wave theory, and the sediment balance equation. Particularly, the suspended load is included into the present numerical model, so that it may be possible to estimate the migration of mound composed of the mixture sediment accurately. The numerical model is satisfactorily verified by comparison of the numerical results with the field data measured both at Silver Strand mound and at Tauranga mound. The convection-dispersion processes, by which the crest of mound is flatted and moved shoreward at the same time, are generated by the present numerical model very well. In addition, it is found that the migration of mound depends directly on the wave height, the sediment size and the wave period through the analyses on the characteristics of mound migration. The dependence of mound migration on the wave height and the sediment size is relatively stronger than that on the wave period.
