本文利用丹麦水资源与水环境研究所(DHI)研制的DHI MIKE软件中的MIKE11模型,建立浑河流域沈抚段区域一维水动力模型MIKE11HD和降雨径流模型NAM耦合模型。应用流域内的降雨站,水文站实测的流量、水位和降雨资料进行参数率定与模型验证。模拟结果表明,MIKE11HD和NAM耦合模型可以对浑河流域沈抚段区域降雨径流、河网水流进行较好的模拟,为实现浑河流域沈抚段区域水质全面提升和水生态功能建设提供水文资料预测的技术支持。
In this paper, MIKE11 model of DHI MIKE software developed by the Danish Institute of Water Resources and Hydrology (DHI) was used to establish the NAM coupled model of one-dimensional hydrodynamic model MIKE11HD and rainfall-runoff model in Shen-Fu Section of Hunhe River Basin. Application of rainfall stations in the river basin, hydrological stations measured flow, water level and rainfall data for parameter calibration and model validation. The simulation results show that the MIKE11HD and NAM coupling model can simulate the rainfall runoff and river network flow in the Shen-Fu Section of Hunhe River Basin, and provide hydrological data for the purpose of realizing the overall improvement of water quality and the construction of aquatic ecological functions in the Shen-Fu Section of Hunhe River Basin Predictive technical support.
