新安江-海河模型在清漳河流域的应用

Application of Xin'anjiang-haihe model in Qingzhanghe river basin

针对北方河道洪水初期比较干枯的情况,以及人类活动对产汇流影响等特点,文中采用修订的新安江-海河模型应用于清漳河流域,对匡门口站多年洪水资料进行产汇流模拟。结果表明,在考虑了海河流域的特性,新增地下水和河道初损等参数的新安江-海河模型达到了预报精度,参数取值合理、模型结构较完善,径流量合格率高于洪峰的预报结果符合清漳河流域的特性,可以将径流量预报进行实际应用。

According to the characteristics of the drought condition of river channel in initial flood period in North China and the influence of human activity on runoff generation and flow concentration, the revised Xin'anjiang-haihe model is used in the Qingzhanghe river basin to simulated the runoff generation and flow concentration of Kuangmenkou station with multiyear flood data. The results show that, considering with the characteristics of Haihe river basin, the Xin'anjiang-haihe model adding the new parameters of underground water and initial loss of river channel could reach the forecast precision. The values of parameters are reasonable and the model structure is perfect. The forecast results with the higher eligibility rate of runoff than the flood peak are accord with the characteristics of Qingzhanghe river basin, the forecast of runoff could be put into the practical application.
