新安江模型在无资料流域冷水河的应用研究

Xin′an River Model Application Research in the Absence Data of Lengshui River Basin

新安江模型是中国第一个完整的流域水文模型,模型结构设计为分散性的,分为蒸散发计算、产流计算、分水源计算和汇流计算4个结构层次。为探索模型在无资料流域的应用,采用冷水河流域附近水文站资料建立三水源新安江模型,率定模型参数,移植区间SMS_3、LAG_3参数构建冷水河洪水预报方案。经检验,方案确定性系数0.909,各预报项目合格率66%以上,精度等级为丙级。得出了三水源新安江模型参数移植在无资料流域冷水河有适用性的结论。可资缺乏资料的中小流域洪水预报方案研制借鉴。

Model of Xin′an River is China′s first full of watershed hydrological model,model for decentralized structure design,calculation is divided into evaporation,runoff,water points calculation and confluence calculation structure of four level.For the application of exploration model basin in the absence of no data,using Lengshui River watershed hydrologic data establishing the model of Xin′an River Three Water model near rate parameters,transplant interval SMS_3,LAG_3 parameters build Lengshui River flood forecasting scheme.Upon examination,the scheme of deterministic coefficient of 0.909,the forecast project qualification rate of 66%above,precision grade for class c.It is concluded that Xin′an River Three Water model in the Lengshui River basin in the absence of no data model parameter transplants have applicability of the conclusion.Possibility of the lack of information medium and small basin flood forecast scheme developed using for reference.
