【Abstract】 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.更多还原
