An Application Research of Rainfall-Water level Forecast Model Based on BP Network
基于BP网络的降雨-水位预报模型应用研究

In this paper,the adaptive adjustment algorithm of the momentum and learning rate of BP Network is improved. The structure of BP network and the data processing method of flood forecast model are discussed. In order to predict the flood water level directly,the rainfall-water level forecast model is built. Furthermore,a new modeling scheme,in which the point rainfall data are used as the model input,is proposed,and the accuracy of BP network is improved.
