摘要：
An absorbing boundary condition is formulated and applied to the one-dimensional open channel flow equations in conjunction with an explicit MacCormack scheme. The physical flow domain has been truncated by introducing an artificial pseudo-boundary. By using an appropriate boundary condition on a truncated domain, it is shown that, for flow containing shocks, the solution can be accelerated to its stationary profile with no loss of accuracy.
