Development of a numerical model for simulating tidal and wave-induced currents in coastal inlets

Proceedings of the Seventh International Conference on Hydroscience and Engineering, Philadelphia, PA, September 2006. http://hdl.handle.net/1860/732An advanced numerical solution scheme has been developed to solve the two-dimensional shallow water equations for simulating coastal hydrodynamics driven by tides and waves in estuaries and coastal inlets. The shallow water equations are discretized implicitly by the control volume approach, and the resulting linear algebraic equations are solved by a penta-diagonal solver. To confirm the capability and efficiency of the numerical model, the numerical applications in the paper are focused on the simulations of currents induced by tides and spectral waves in coastal inlets. By running the model connected with a wave module steered by the SMS (Surfacewater Modeling System) interface, the obtained numerical results show that this model could run not only with a large time increment, but also stably and robustly in all application simulations
