【摘要】：將感潮河段退水曲線視作上游洪水波退水與下游潮水波頂托2種獨(dú)立過程雙向運(yùn)動的疊加,根據(jù)洪水波退水公式和調(diào)和分析方程建立感潮河段雙向波退水曲線耦合模型。以姚江入江口段姚江大閘次洪退水過程為研究對象,對2008-2016年15場次洪水退水段進(jìn)行了模擬。結(jié)果表明:各次洪退水段模擬的洪水波參數(shù)取值較穩(wěn)定,說明退水規(guī)律較好;潮水波影響系數(shù)的大小與河道水位、降水以及天文大潮的出現(xiàn)有關(guān);雙向波退水曲線耦合模型能夠較好地模擬姚江流域出口的退水過程。
[Abstract]:In this paper, the receding curve of tidal reach is regarded as the superposition of two independent processes of upstream flood wave receding and downstream tidal wave topping, and a coupling model of bidirectional wave receding curve is established according to flood wave retreating formula and harmonic analysis equation. In this paper, the process of secondary flood receding from Yao River sluice in the mouth of Yao River is taken as the research object, and the 15 flood receding sections from 2008 to 2016 are simulated. The results show that the parameters of the simulated flood wave in each flood receding section are stable, which indicates that the law of receding water is good, the influence coefficient of tidal wave is related to the water level of river, precipitation and the appearance of astronomical spring tide. The coupling model of bidirectional wave regression curve can well simulate the process of water withdrawal at the outlet of the Yao River basin.
