The process of deposition at the mouth bar of the Yangtze River estuary is a very complex process.In this paper,the elevation variance of the mouth bar is considered as a stochastic process that is affected by many factors.A mathematical model of multiple regression is developed.This model is correct and reliable based on the synthetical analysis of significance of the regression equation,multiple correlation coefficient and standard deviation.The fitted computation is performed using the mathematical model and the result.It shows that the fitted value conforms to the observed data.Thus,the mathematical model can predict the changing tendency at the mouth bar,which is caused by various changes of flow and sediment discharge for construction of the Three Gorges Project.
