分别采用新安江模型、HEC模型和TOPMODEL模型对滦河宽城流域进行洪水模拟计算,认为蓄满产流模型可以进行半干旱地区洪水模拟和预报分析,在计算时段为3 h的情况下,采用历史水文资料无法区别出产流模式.如果采用超渗产流一类的模型,计算时段要小于0.5 h.
The Xin’anjiang model, HEC model and TOPMODEL model are respectively used to simulate the flood in the Luanhe Kuancheng River basin. The model of the floodplain production in the semi-arid area can be used to simulate and predict the flood in the semi-arid area. When the calculation period is 3h, Historical hydrological data can not distinguish between the production flow model.If using a model of ultra-seepage flow, the calculation period is less than 0.5 h.
