The object of research is Chaping River which flows over Anxian County in Mianyang City, Sichuan Province. Based on a great number of investigations on the load of water pollutants, the situation and function of water environment of the river, the river-basin hydrological character, the river draining plan , and observation date at environmental monitoring station of Mianyang City Sichuan Province in 2005, two-dimensional hydrodynamic shallow-water model equations were used for monitoring COD and NH3-N concentrations in section of the Chaping River and the simulations were compared. A one-dimensional model was used to calculate the water volume capacity of the river's water environments and the ways controlling the total quantity were provided. Results indicated that using two-dimensional hydrodynamic shallow-water model equations to calculate the monitoring section showed a small measured difference for COD and NH3-N. For the water environmental capacity of Chaping River, COD was 123.96 t/a and NH3-N 42.95 t/a. The COD and NH3-N emission volume would exceed the capacity in the basin, and the quality of output water would exceed theⅢgrades of water protecting standards.
