A finite volume turbulence model for the resolution of the two‐dimensional shallow water equations with turbulent term is presented. After making a finite volume discretization of the depth‐averaged k –ε equations in conservative form, the q – r equations, that give stability to the process, are obtained. Wall and inlet boundary conditions for the turbulent equations and wall conditions for the hydrodynamic equations are discussed. A comparison between the k –ε and q – r models and some experimental results is made. Copyright © 2008 John Wiley & Sons, Ltd.
