摘要
为保障世博园区水安全、研究河网水力要素的时空变化过程及感潮河网水动力变化特性,应用MIKE11水环境模型软件,构建并改善了白莲泾区域水量(水文、水动力学)水质模型,并对模型进行重新率定、验证,所得计算值与实测值吻合较好。应用模型模拟了"6.29大雨"白莲泾区域的河道水量水质,提供了最优的泵闸联动调水方案。可为制定、优化调水方案和建立水资源环境管理决策支持系统提供科学依据。
The spatial and temporal variation process of hydraulic elements of river network and the hydrodynamic characteristics of tidal river network are studied to ensure water safety in world exposition areas. Water environment mod- eling software MIKE11 is used to establish water quantity(hydrology, hydrodynamic) and water quality model of Bailian- jing region. And the model is calibrated and verified. The simulation results are close to measured value. Finally, the model is applied to simulate river water yield and quality of Bailianjing region under 6.29 heavy rain. At the same time, joint optimal scheme for water diversion-interaction of gates and pumps can be obtained. Thus, it can provide scientific basis for building the decision support system of water resources environment management and optimal water diversion schemes.
