【摘要】：将感潮河段退水曲线视作上游洪水波退水与下游潮水波顶托2种独立过程双向运动的叠加,根据洪水波退水公式和调和分析方程建立感潮河段双向波退水曲线耦合模型。以姚江入江口段姚江大闸次洪退水过程为研究对象,对2008-2016年15场次洪水退水段进行了模拟。结果表明:各次洪退水段模拟的洪水波参数取值较稳定,说明退水规律较好;潮水波影响系数的大小与河道水位、降水以及天文大潮的出现有关;双向波退水曲线耦合模型能够较好地模拟姚江流域出口的退水过程。
[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.
