摘要

摘要

En 中文
We consider the Laplace transform filtering integration scheme applied to the shallow-water equations, and demonstrate how it can be formulated as a finite-difference scheme in the time domain. In addition, we investigate a more accurate treatment of the nonlinear terms. The advantages of the resulting algorithms are demonstrated by means of numerical integrations.
