Abstract

The propagation and evolution of surface gravity waves were studied by using the spectral version of the discontinuous Galerkin method. It was observed that the spectral/hp element approach can generate computationally competitive models for coastal and hydraulic engineering. In solving the momentum equations the coupled momentum equation is rewritten as a scalar wave continuity equation thereby reducing the size of the resulting sparse matrix system. It was also found that the spectral/hp element method reduced the computational time for large-scale long-time dispersive wave simulations.
