摘要
A Fulx Difference Splitting (FDS) scheme was used in a 2D depth-averagedflow-pollutant model. Within the framework of the Finite Volume Method (FVM) a 2D simulation wastransferred into solving a series of local ID problems based on the rotational invariance propertyof the flux. The FDS scheme was employed to estimate the normal numerical flux of variablesincluding water mass, momentum and pollutant concentration across the interface between cells. Thescheme was checked with exact solutions and verified by observations in the Nantong reach of theYangtze River. Calculated results well match both exact solutions and observations.
