| Abstract: | This paper analyzes the factors influencing the distribution of canal or river cross section and formulates the empirical exponential function which can reflect flow characteristics and shape of river cross section. The parameter calibration method and velocity forecasting function are proposed. The successful application to river closure of the Three Gorges Project indicates that the accuracy of this method is fairly high. |
