新安江模型与垂向混合产流模型的比较

Comparison of Xin'anjiang model with vertically-mixed runoff model

从实时洪水预报模型通用性角度出发,对新安江模型与垂向混合产流模型进行比较研究.选用青峰岭水库流域、危水水库流域资料分别采用这两个模型进行模拟计算.计算结果表明,在湿润地区,新安江模型和垂向混合产流模型都能取得好的成果;在半干旱地区,新安江模型应用效果不太理想,垂向混合产流模型能取得比较令人满意的结果.

A comparison of the Xin'anjiang hydrologic model with the verticallymixed runoff model is made from the viewpoint of universality of a realtime flood forecasting model. With the two models, simulation and calculation are performed for the Qingfengling Reservoir basin and the Weishui Reservoir basin by use of the observed data. The results show that both of the two models can yield good results for humid areas, but for semiarid areas, the result from the Xin'anjiang model is not satisfactory, while good results can still be obtained from the verticallymixed runoff model.
