摘　　要：感潮河段洪水波运动，受潮汐影响，且流量观测资料误差也大，由流量预报再转换为水位，很难达到理想的效果．本文据水量平衡和蓄量水位关系，导出感潮河段的水位演算基本模型，通过上游洪水波和下游潮水波的分离演算、组合叠加，直接预报河道洪水位，既简化了预报方法，又提高了预报精度．n the tidal effected river, it is usually not easy to measure exactly the time dependent river discharge. The river water stage is thus difficult to be predicted with the expected accuracy by the conventional method by which the river discharge is first estimated and the water lesel is then obtained from the discharge. In this paper, a stage routing model is developed based on water balance equation and stage storage relation. The model could be applied directly to forecast the river water stage which is affected by both the up stream flood wave and the down stream tidal wave.
