Well-Balanced Second-Order Finite Element Approximation of the Shallow Water Equations with Friction Academic Article uri icon


  • 2018 Society for Industrial and Applied Mathematics. This paper investigates the approximation of the shallow water equations with topography and friction, using continuous fnite elements. A new, second-order, parameter-free, wellbalanced and positivity preserving explicit approximation technique is introduced. The novelties of the method are the explicit treatment of the friction term, the robust approximation of dry states, a commutator-based, high-order, entropy viscosity, and a local limiting procedure. The computational method is illustrated on various benchmark tests.
