| Abstract: |
| In this paper,the importance and the role of flood forecasting in decision-making of river flood control are briefly described.ANN models for peek discharge forecasting of the floods at Lintong and Huaxian sections in lower reach of the Wei River are developed.It is shown through calibration and verification of the models that the precision of the ANN models is obviously higher than that of traditional statistical models.The ANN models are convenient for rational balance of the precision of calibration and verification of the model and appropriate for intelligent management of flood forecasting and flood control decision-making. |
