Coastal Simulation with an Integrated Wave-Current-Sediment Model
Publication: World Environmental and Water Resources Congress 2024
ABSTRACT
A general wave-current-sediment interaction model SRH-Coast has been developed with improvements over the existing models. SRH-Coast uses a single unstructured mesh for all three sub-models—current flow, wave, and sediment. It also integrated the three models into a single model using a semi-implicit coupling method. The current flow solver is based on the existing SRH-2D hydraulic model, the wave model follows the approach of SWAN which solves the multi-frequency multi-direction wave action balance equation, and the sediment module solves the non-uniform non-equilibrium sediment equations. In this paper, the governing equations and the numerical methods are described; the model is then verified using laboratory cases. Good matches of the model predictions with the measured data are obtained.
