High- Resolution Numerical Model for Shallow Water Flows and Pollutant Diffusions

摘要：

A high-resolution numerical model for coupling the shallow water flows and pollutant diffusions was presented based on using the two-step finite-volume component-wise TVD (total variation diminishing) scheme, by which second-order accuracy in both time and space is achieved. Numerical simulations for open channel flow and pollutant dispersion were implemented and compared with experimental data. The validation of this method shows that it can not only deal with the problem involving discontinuities and unsteady flows, but also solve the general shallow water flows and pollutant diffusions.
