中文摘要：
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3h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0．5h．
英文摘要：
The three hydrological models, i.e. the Xinanjiang model, HEC model, and TOPMODEL were applied to flood simulation for Kuancheng basin of the Luanhe River, which is a semi-arid region, and satisfactory results were obtained even though the mode of runoff yield of the three models was the type of runoff yield under saturated storage. The analysis of the results demonstrates that the mode of runoff yield could not be distinguished from the historical hydrological data under the calculation interval of 3 h, and that the calculation interval should be less than 0.5 h if the model for runoff yield under excess infiltration is used.
