摘要: 运用半分布式HBV水文模型,选取藉河流域2006—2013年水文资料、气象资料在渭河一级支流藉河天水(二)站水文站以上流域建立降水-流量-水位关系,确定流域致灾临界面雨量。结果表明,HBV模型在率定期Nash系数为0.50,确定性系数R2为0.70;在验证期Nash系数为0.71,确定性系数R2为0.84。根据天水(二)站水文站实测流量数据以及HBV模型水位-降水关系,对流域致灾临界面雨量进行确定,并选择3次洪水过程进行验证,证明基于HBV水文模型方法确定的致灾临界面雨量指标预警效果良好。

Abstract: Using semi-distributed HBV hydrological model, the hydrological data and meteorological data of Jihe River Basin from 2006 to 2013 were selected in the first-level tributary of Weihe River Jihe Tianshui(II) hydrological station. The relationship between precipitation, discharge and water level is established in the basin above the hydrological station, and the precipitation at the precipitation-induced interface is determined. The results show that the Nash coefficient of the HBV model is 0.50 and the deterministic coefficient R2 is 0.70. The Nash coefficient is 0.71 and the deterministic coefficient R2 is 0.84 in the verification period. According to the measured discharge data of Tianshui(II) hydrologic station and the relationship between water level and precipitation in HBV model are used to determine the rainfall at the interface of basin disaster, and the three flood processes are selected to verify it. It is proved that the early warning effect of the rainfall index of the disaster interface based on the HBV hydrological model method is good.
