Abstract

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. This work was partially supported by the Russian Foundation for Basic Research (project 11-01-00767а).
