A modified BP algorithm with peak recognition theory (BPPR) is proposed for improving the calculation of artificial neural network. By this algorithm the error correction of flood peak value is mainly depending on the modification of weight according to the error of the big values. It is useful to improve peak value recognition the accuracy of flood forecasting.
