摘要: On large geographic scales, ocean waves are represented in a spectral sense via the action balance equation, which propagates density through both and space. In this paper, new computational wave model is developed by using discontinuous Galerkin (DG) methods DG allow for use of unstructured meshes higher-order approximations propagation space, we show leads to increased accuracy. This verified validated comparisons manufactured analytic solutions as well Simulating WAves Nearshore (SWAN) model. Coupled wave/circulation models needed many applications including interaction between currents during daily wind tide driven flows. We loosely couple Shallow Water Equation Model (DG-SWEM), an existing circulation addition formulating method coupled model, derive priori error estimate. Preliminary numerical results presented with DG-SWEM tightly SWAN.
