An algorithm for solving a finite-difference scheme that approximates the shallow water equations with a nonlinear part on unstructured grids is proposed. A comparison of the numerical results obtained for nonlinear and linear cases is discussed. The effect of “bad” grid elements on numerical results is analyzed.
Keywords: shallow water equations; nonlinear tidal wave equations; finite difference schemes on unstructured grids.
