Abstract: A depth-averaged 2-D model of open-channel flow has been established by solving the 2-D shallow water equations using an implicit finite volume method on a non-orthogonal, non-staggered, curvilinear grid. The convection terms are discretized with four upwind schemes. The SIMPLEC algorithm is employed with Rhie and Chow’s momentum interpolation method to achieve the coupling of pressure and velocity on the non-staggered grid. The model has been applied to simulation of dam-break flow. The simulated water levels and velocities are in good agreement with measurement data.
