At the same time, the WEC (Water Environment Capacity) is simulated by WASP6 for Weihe River. The value of WEC is about 141830.3kg/day, the amount of pollutants flowing into river should be cut 77.2% at 90% probability of flow.

• 并应用WASP6水质模型模拟计算了渭河干流的水环境容量，在90%25流量保证率下，渭河干流陕西段的COD_(Cr)环境容量为141830.；3kg/day，达到水环境规划目标应削减现有污染物排放量的77
