| 摘要: |
| 感潮河段水流受多种因素影响,呈现出复杂的周期性,具有不恒定往复流动的特征,且河道地形资料难以获得.考虑充分利用已有水位实测资料,采用以洪潮分离为出发点的双向波方法建立感潮河段水位演算模型,介绍该模型基本方法以及在有支流和区间入流汇入等不同情况下的改进方法.根据飞云江感潮河段的具体特点,利用新安江模型计算区间流量过程,针对不同级别的洪水进行水位分级和退水段独立模拟,证明该模型在感潮河段水位演算中具有良好的可靠性和适用性. |

| Abstract: |
| The flow of tidal reach is affected by many factors,with complex periodicity and unsteady reciprocating movement.The topographical data of tidal reach is not available easily.In order to make full use of water level data,a stage routing model for tidal reach is established based on the bidirectional wave method.The basic principles and the improved method of the model are presented,including the way how tributary and local inflows are treated.Based on the specific characteristics of the Feiyunjiang tidal re... |
