应用MIKE11模型系统建立了以苏州河及其支流为重点的全市感潮河网水动力数学模型。模型在天然河网的基础上,以骨干河道为基础,进行合理的河道和湖泊概化,并将上海市河网水系划分为14个水利片,分片考虑区域降雨径流对河网水量的影响。模型可应用于水系水量调度分析及非点源污染分析,并对对苏州河沿岸泵站雨天溢流进行模拟计算。结果表明,建立的苏州河水系水动力模型可为苏州河整治工程提供科学决策工具。
The MIKE11 model system is used to establish the hydrodynamic model of the tidal river network focusing on Suzhou River and its tributaries. On the basis of natural river network, the model makes reasonable river and lake generalization based on the main channel, and divides the river network of Shanghai into 14 water conservancy tablets. The model considers the influence of regional rainfall runoff on river network water . The model can be applied to the analysis of water system and the analysis of non-point source pollution. The model is also used to simulate the rainy day overflow of pump stations along the bank of Suzhou Creek. The results show that the established hydrodynamic model of Suzhou Creek can provide a scientific decision-making tool for the Suzhou River Regulation Project.
