| Abstract: | in real-time flood forecast, we used the least squares estimates recurrently and autoregressive model Of errors to correct parameters of the model and their predicted value respectively. By using two-stage correction to improve predicted preeision,it has been verified through an example of Dachaoshan catchment on hancangjiang river.And a high accuracy can be obtained. |
