| Abstract: | Law of the flow change and long-range prediction of annual top flood peak on Jiagedaqi Station of Ganhe River is discussed in this paper,Based on wavelet transforms.It indicates that law of the flow change of annual top flood peak on Jiagedaqi Station has a characteristic with multi-time scale,and its main periods are 4 a,6 a and 27 a.Harmonic wave prediction method is provided based on wavelet transforms. |
| Keywords: | annual top flood peak wavelet analysis period long-range prediction |
