摘要
结合潮汐数据的规律性,利用人工神经网络建立吴淞口逐时潮位之间的非线性关系,从而对吴淞口潮位进行短期预报。实例证明,非风暴潮期间,这种方法的预报精度符合水文情报预报标准,6h以内的预报精度较高。
Combining with the regularity of tide data,the paper sets up non-linear relation among the hourly tidal levels of Wusong estuary,does short-term forecast of tidal level using BP neural network.The result shows the accuracy of forecast could meet the standard for hydrological information and hydrological forecasting during non-storm surge period,especially the accuracy of forecast within 6 hours is high.
