感潮河段双向波水位演算模型验证

Verification of the bi-directional stage routing model for a tidal river

  • 摘要: 假设感潮河段洪水位可以视作上游洪水波和下游潮水波双向传播后的叠加,根据从水量平衡方程和槽蓄方程推导出的水位演算基本方程建立感潮河段双向波水位演算模型。通过建立理想模型采用3个试验对双向波水位演算模型的洪潮分离假设条件、模型稳定性、合理性及有效性进行分析,来论证洪潮分离理论的可行性。结果表明,基于洪潮分离理论假定建立的双向波水位演算模型结构合理,模拟精度较高。

     

    Abstract: If it is assumed that the flood and tidal waves in a tidal river are independent of one another, river stages can be considered as the superposition of bi-directional propagation, namely flood waves from the upstream and tide waves from the downstream. Based on the assumption, a bi-directional stage routing model (BSM) for a tidal river is developed according to the basic stage routing equation derived from the storage equation and the water balance equation. In order to prove the feasibility of the separation of flood and tidal waves, three tests are conducted by using the approaches of the ideal models to analyze the assumption, stability, rationality and validity of the BSM. The results show that the structure of the BSM is reasonable, and its performance is satisfactory.
