摘要：
In this paper we study a Lax-Wendroff-type time discretization procedure for the finite difference weighted essential non-oscillatory (WENO) schemes to solve one-dimensional shallow water equations with source terms. Extensive simulations are performed, as a result, the WENO schemes with Lax-Wendroff-type time discretization can maintain nonoscillatory properties and more cost effective than that with Runge-Kutta time discretization.
