改进垂向混合产流模型在营口洪水模拟中的应用

The application of vertical mixed flow model in Yingkou flood simulation was improved

为分析改进的垂向混合产流模型在营口地区河流洪水模拟的适用性,以营口地区熊岳站为研究实例,结合熊岳站15场典型实测洪水数据对比改进前后模型的模拟精度。分析表明:改进的垂向混合产流模型在熊岳站模拟精度总体可达乙级标准,在洪峰和洪量模拟精度均较传统模型有着较为明显的改善。研究成果对于营口地区洪水预报方案制定具有重要参考价值。

In order to analyze the applicability of the improved vertical mixed runoff model in river flood simulation in Yingkou area,the Xiongyue station in Yingkou area was taken as a research example,and the simulated accuracy of the model before and after the improvement was compared with 15 typical measured flood data of Xiongyue station.The analysis shows that the improved vertical mixed runoff model can reach the B-level standard in the simulation accuracy of Xiongyue Station,and the simulation accuracy of flood peak and flood volume is obviously improved compared with the traditional model.The research results have important reference value for the formulation of flood forecasting schemes in Yingkou area.
