We consider in this work an expanded finite volume numerical approximation of the turbulent shallow water equations, on unstructured meshes, we use a simple discretization in wish only physical fluxes and averaged states are used in their formulations. To control the local diffusion in the scheme and also to preserve monotonicity, a parameter is introduced based on the sign matrix of the flux Jacobian. Numerical results are presented and compared with experimental data, for a backward-facing flow problem, to demonstrate and confirm its capability to provide accurate simulation of turbulent flows.
