The characteristics of complex flooding,analyzed the from time,cannot fully reflect the characteristics.According to Morlet wavelet analysis,this paper has analysis the characteristic of the flood series.This paper showed that: the characteristics,which of the peak flow process and the flood of evolution process,can be reflected from the frequency information.The size of frequency with the flood of evolution process has reflected the different information of flood evolution process by wavelet time-frequency transform.Time-frequency analysis results can effectively extract peak flow process.The peak flow process in frequency domain,can effectively reflect the flood peak flow process.
