Newell, C. and Mullarkey, T., 2007. Wave-Current Interaction Involving Iteration between Finite Element Wave and Current Models. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 773 – 777. Gold Coast, Australia, ISSN 0749.0208

A wave-current interaction model has been developed by the authors. The wave sub-model uses the elliptic form of the mild slope wave equation in the domain and the parabolic form of the mild slope equation as an absorbing boundary condition. A set-up/set-down and current sub-model uses radiation stress values as a driving force. These are obtained from the velocity potential results, including breaking, of the wave sub-model. The wave sub-model includes wave-current interaction and hence an iterative solution scheme can be carried out between the two sub-models to achieve accurate results of wave behaviour in the coastal zone. The results of this paper show that wave-current interaction is accurately modelled by the wave sub-model and that the overall iterative solution scheme provides accurate results for wave behaviour in the coastal zone.
