Abstract

An implicit finite difference solution is used to study the dynamic effects of tidal flows on suspended load transport. The numerical method solves transformed forms of one- dimensional equations for sediment concentrations over the water column in order to reduce truncation errors. Applications are made to analytical and field situations and shown to yield good results. Parametric simplification of model results combined with field data on suspended load is used to suggest improvements to existing morphological 3D (Box) models for prediction of seabed change due to tidal action. 1 Introduction The recent development of soft methods of coast protection, which may also be combined with sediment retention structures, is placing greater demands on design methods than in the
