An approach to medium-term coastal morphological modelling

This thesis presents the implementation of fully three-dimensional sediment transport and morphological updating formulations within a proven three-dimensional hydrodynamic flow solver. The thesis briefly discusses the formulations used to model both suspended and bed-load transport of non-cohesive sediment, and describes the implementation of a morphological updating scheme which incorporates novel approaches to morphological acceleration and dry bank erosion. Approaches used to model the three-dimensional effects of waves on coastal hydrodynamics and of three-dimensional currents on waves are also discussed.Results of several validation studies are presented and the model is shown to perform well in a series…
