摘要：
In this paper we consider the flow in an open channel, where super-critical flow may be induced by the geometry of the channel. The scheme presented calculates the Riemann invariants along characteristic curves and hence has no CFL limit. The presence of source terms may lead to a restriction on the time-step though, to ensure the stability of the ODE solver used. A high order monotone interpolation is used to provide accuracy whilst not inducing oscillations at hydraulic jumps. © 1993 Academic Press, Inc.
