Application of an efficient hydraulic model for surface water flows

Abstract

In this work, we consider the numerical simulation of free flow by numerical resolution of saint-venant's equations, which form a nonlinear hyperbolic system. The numerical approximation model equation is discretized by the finite volume method, the computational mesh is unstructured triangular and dynamically adaptive. The numerical adjective flows were evaluated by Roe approximate Riemann solver, the time integration is meant for a Runge-Kutta. The source term was discretized by an upwinding scheme of Vazquez.
