基于MIKE11模型的城市引配水方案研究——以宁波市区鄞东南平原为例

Research on Water Transfer Scheme in Urban Area Based on MIKE11 Software:Taking Southeast Yinzhou Plain of Ningbo City as an Example

城市化建设的快速发展对城市河道水环境产生一定影响,为提高河道水生态环境,满足人民群众对高品质生活的愿望,拟开展河网引配水研究工作。以宁波市区鄞东南平原为研究对象,基于MIKE11一维水量水质耦合模型构建城市河网引配水模型,分析论证不同引水水源水质、引水规模、引水闸泵布置方案下的水动力特性与水质改善效果,确定合理的引水水源水质、引水规模与闸泵布置方案。

The rapid development of urbanization construction has had a certain impact on the urban river water environment.In order to improve the river water ecological environment and meet the people’s desire for a high-quality life,it is planned to carry out the research on water diversion and distribution of the river network.Based on the MIKE11 one-dimensional water quantity and water quality coupling model,this paper constructs a water diversion and distribution model of urban river network,and analyzes and demonstrates the hydrodynamic characteristics and water quality improvement effects under different water diversion water source quality,water diversion scale,and diversion gate pump layout scheme,so as to determine the reasonable water quality of water diversion sources,water diversion scale and gate pump layout scheme,and provide reference for urban river water environment management.
