We present a high-order discontinuous Galerkin model for solving the two-dimensional shallow water equations on unstructured triangular meshes. The model uses orthogonal Dubiner expansion basis of arbitrary polynomial order in space and a third-order Runge-Kutta scheme in time. Using numerical computations of a standing wave we illustrate that the model exhibits exponential convergence for smooth problems. Finally, an example of computation of harbour resonance is presented.
