Wavelet neural network is a powerful tool for rainfall-runoff (RR) prediction. In this essay, a neural network based on wavelet function was proposed. But due to the probability of reaching local minimum of WNN, an improved simulated annealing neural network SAWNN was used in comparison of the WNN, the SAWNN has the ability of reaching the global minimum by employing the disturbing function and is able to mapping non-linear relations. Results show that the SAWNN has ideal performance in RR simulation and has small training error. It also indicates that the training samples should contain as much samples in different condition as possible.
