One-dimensional conservative coupled discretization of the shallow-water with scalar transport equations
2008
The quality of the solutions obtained by numerical methods in shallow-water equations is strongly dependent on the discretization used. This is the greatest difficulty in shallow-water simulations. In this work we showthat only a coupled discretization of the whole system of equations and a careful definition of the flux limiter function in second order TVD schemes are necessary in order to preserve uniform solute profiles in situations of 1D unsteady subcritical flow.
