Research on sediment-carrying capacity based on theory of BP neural network
Hongwu Tang · Journal of Sediment Research · 2004
According to the analysis of factors influencing on the sediment-carrying capacity, it is concluded that formulas of Wuhan Univerisity and Dou Guoren's formula are identical from the viewpoint of Artificial Neural Network (ANN). The factors which should be considered in BP training are found and program is compiled by C++ Builder. Good agreements are obtained by training 30 runs of lower concentration, middle concentration and hyproconcentration flow. The conjunctional functions are memoried and used to predict the other 4 runs' sediment-carrying capacity. The differences between the predicted and measured are also slight. It is recommended that using ANN to estimate sediment-carrying capacity be feasible.
