HEC-HMS水文模型在大渡河流域的应用研究
|
摘要
HEC-HMS模型是一个具有半物理机制的半分布式降雨径流模拟模型,在洪水分析和洪水预报中具有广泛的应用。以大渡河流域上游为例,结合流域实测水文气象资料,构建了流域的HEC-HMS模型,基于Morris筛选法确定了模型敏感性参数为CN、初损、滞时以及峰值系数。通过大渡河上游的7场洪水过程对该模型进行了率定验证,结果表明纳什效率系数均在0. 72~0. 88之间,洪峰流量相对误差均小于14. 4%。分析表明该模型在大渡河流域洪水模拟中有较好的适用性。
HEC-HMS is a semi-distributed rainfall-runoff hydrological model with semi-physical mechanism,which is widely used in flood analysis and flood forecasting. A HEC-HMS model of the Dadu River Basin is constructed based on the hydrological and meteorological data. CN,initial abstraction,lag time and peaking coefficient are the major sensitive parameters for the model determined by Morris screening method. The established HEC-HMS model is calibrated and verified by seven typical historical floods in the upper reaches of the Dudu River. The results show that the Nash efficiency coefficients are between0. 72 and 0. 88 and the relative errors of the peak flow are less than 14. 4%,which indicates that the model is suitable for hydrological simulation of the Dadu River Basin.
