| Abstract: | By using the historical database which contains large amount of hydrological data and feedback information,a flood forecasting model is designed and established based on decision tree C4.5 algorithm and existing researches.The water level of Taihu Lake is forecasted with the model as a case study.The result shows the model has a clear structure and simple prediction rule,and also has a high accuracy in both calibration and validation periods.As a result of data mining,the decision tree used for forecasting ... |
