摘要
为了加强巴基斯坦卡洛特水电站坝址以上巴基斯坦境内吉拉姆河流域性水文建模研究,结合ArcGIS,采用SWAT模型对流域日均流量进行了模拟。结果表明:基于SWAT模型对2017~2019年日均流量的模拟值与实测值吻合较好,模型率定期(2017~2018年)的决定系数R^(2)为0.79,Nash-Sutcliffe效率系数E_(NS)为0.79;验证期(2019年)R2为0.84,效率系数E_(NS)为0.79。SWAT模型在流域内的适用性研究结果达到了预期,有助于提高卡洛特水电站水情预报预测能力,为该流域后续水文特性研究工作打下了良好基础。
To strengthen the hydrological modelling of the basin above the dam site of Karot Hydropower of the Jhe⁃lum River Basin,the SWAT model was used with ArcGIS to simulate the daily average discharge of the Basin.The results showed that the simulated daily average discharge was well conformed with the measured data from 2017 to 2019.The R^(2) and Nash-Sutcliffe efficiency values during 2017 to 2018 calibration period were 0.79 and 0.79,0.84 and 0.79 during 2019 validation period.The satisfactory application of the SWAT model in the watershed can help to improve the flow regime forecasting capabilities for the Karot Hydropower Station and lay a good foundation for the subsequent hydrological characteristics research of the basin.
