| Abstract: | This article presents the principle of ANN briefly in the application of flood forecast and an improved network algorithm of rainfall runoff forecasting. In order to avoid getting a part least and shorten the study time, this article uses the improved self adaptive BP algorithm for flood forecasting, and exploit the system on the base of a BP algorithm in flood forecast. The achievement has been applied in the flood forecasting system of Wenyuhe Reservoir in Shanxi province, and satisfactory results were acquired. |
