Abstract:
Based on analyzing affecting factors of the designed lowest navigable stage, the problem of calculating the designed lowest navigable stage at downstream stretch of hydro-junction is generalized as a nonlinear functional relation between input and output. The back propagation(BP)networks mode calculating the designed lowest navigable stage is established on artificial neural network model principle. The designed lowest navigable stage at Guanyingqi downstream Shuikou dike of Minjiang is calculated by the BP network mode. A comparison between BP network model and the model analysis on observed data is made. The results of two methods are about the same, but the BP network model possesses higher accuracy. Thus a new method is provided for the design of lowest navigable stage at downstream stretch of hydro-junction.
