| 英文摘要 | This paper addresses a problem of flood forecasting with the self-memory function. Considering flood forecasting's uncertainty and updating demand, a hybrid hydrological model, namely Differential Hydrological Grey Model with self-memory function (DHGM-SM), is developed. The model has two fold features. One is to establish a self-memorization equation linked with DHGM, that could extract useful information from past data series and realize updating of hydrological dynamic process. The other is that this model has higher efficiency relative to original hydrological model without self-memory function. This approach was applied to river flow forecasting of two representative basins in Tunxi of South China and Daqinggou of North China. It is shown that this hybrid method has satisfactory forecasting accuracy by examination of both calibration and validation. © 2009 Science in China Press and Springer-Verlag GmbH. |
