基于MIKE11模型的河网模拟计算在中小河流整治中的应用——以乌涌中下游段河道整治为例

Application of River Network Simulation Calculation Based on MIKE11 Model in Middle and Small River Remediation——A Case Study of River Regulation in Middle and Lower Reaches of Wuyong County

在我国中小河流整治过程中,常遇到水文测站不足、缺乏实测基础资料、地理环境复杂等难题。如何利用有限的资料更准确、高效地分析模拟河流的水位及水流变化,是中小河流整治亟待解决的问题。该文以乌涌为例,将MIKE11模型与设计洪水计算相结合,模拟河道水面线并得到堤岸淹没区,针对河道水面线现状提出相应整治措施。通过实例验证,此方法有效、可行,可为中小河流整治提供参考和思路。

In the process of remediation of small and medium-sized rivers in China,problems such as lack of hydrological stations,lack of basic data for observation and complicated geographical environment often exist.How to use the limited data to analyze the water level and the change of water flow more accurately and efficiently is an urgent problem to be solved in middle and small rivers.In this paper,Wuyong is taken as an example to combine the MIKE11 model with the design flood calculation to simulate the water surface of the river and obtain the embankment inundation area.Corresponding treatment measures are put forward according to the current status of the water surface of the river.Through the example verification,this method is effective and feasible,which can provide references and ideas for medium and small river regulation.Keywords:MIKE11 model;river network si
