In this paper two second-order accurate finite-difference explicit schemes are introduced for the solution of two-dimensional shallow-water equations. These schemes are second-order accurate in both space and time and predict the location and height of the bores without requiring shock fitting and allow simulation of both subcritical and supercritical flows, and the inclusion of initial conditions having sharp discontinuities. Steady state flows may be analyzed by using these schemes by continuing computations until they con- verge to a steady state subject to the specified end conditions. Fennema and Chaudhry (1986, 1987) applied these schemes for the solutions of a number of one-dimensional open-channel flow problems. The governing differential equations are first presented. Details of the finite-difference schemes, sta- bility conditions, and the inclusion of boundary conditions are discussed. The schemes are applied to analyze two typical hydraulic problem,and re-sults are presented for illustration purposes.
