基于MIKE11的浑太河水动力水质模型研究

Research on Hydrology and Hydrodynamic Model in Huntai River Based on MIKE11

基于MIKE11构建了浑太河流域主干河流—浑河、太子河水动力水质数值模型,并对浑河闸、葠窝水库两座大型水利工程进行概化处理,利用长序列逐日水文资料对模型参数进行率定与验证。研究结果表明,水动力、水质及可控制水工建筑物模拟精度高、拟合效果好,能够充分反映研究河段水动力及水质特征,可为水质预测、水质水量联合调度等水利工程相关研究提供模拟响应工具。

Based on MIKE11,this paper established a hydrology and hydrodynamic coupled numerical simula-tion model researched on Hun River and Taizi River Basin. Multiple methods are used to insure this model ＇s precision：Firstly,in order to add Hun River sluice gate and Shenwo reservoir for controllable hydraulic archi-tecture simulation the paper applied a data generalization way.And then a long sequence hydrologic data was appied in calibration and verification for sensitive parameters during simulating.Results show that the coupled model is accurate and reasonable, also it can adequately reflect Hun and Taizi River Basin ＇s hydraulic and self-purification feature.In the engineering field of water quality research and dam operation,this paper possesses applied value.
