摘要
本文利用有限差分法分别求解二维浅水方程组和对流扩散方程.模拟鄱阳湖的典型湖流流场和湖水中有机污染物(COD)的浓度场.计算结果与实测数据颇为接近.
This paper adopts the finite-difference method to solve the two-dimensional shallow water equations and the advection-diffusion equation respectively, simulating the typical lake currents and organic pollutant (COD) distribution of Poyang lake. The simulation result is in good agreement with the actual data.
