中文摘要：
将感湖河段预报断面的洪水过程视作上游洪水波和下游潮水波双向传播后的叠加，两个传播过程分别应用水位演算方法进行模拟计算，再结合多元线性回归法，以此建立同时受多个主要上游洪水及下游潮汐影响的水位预报模型。该模型方法简单，物理概念清楚。本模型在椒江感湖河段临海站的水位预报过程中取得了良好的效果。
英文摘要：
In this study, the flood hydrograph at the forecasting section of tidal reach was considered as the superposition between flood waves from upstream and tide waves from downstream after bidirectional propagation. By using the multivariate linear regression analysis method, the propagation process was calculated with stage forecasting model for the tidal reach, so as to set up the stage model dealing with the influence from upstream flood waves and downstream tide waves. This model is simple with clear physical concept, with which good results have been achieved in stage forecasting at Linhai Station on the Jiaojiang River.
