Abstract:According to the practice needs of Danjiangkou reservoir operation scheduling,the morlet wavelet analysis was used on the hydrological annual runoff,the flood runoff and the dry runoff time series.The morlet wavelet analysis reveal more complex structure of time scales of the Danjiangkou reservoir,and analyzes the runoff cycle and mutation points of different scale runoff series.The results show that time series of the hydrological annual runoff,the flood runoff and the dry runoff have four main cycles of 9,20,40,50 years,and the hydrological annual runoff and the flood runoff have similar cycle evolution characteristics.The results are reference for operation scheduling of the Danjiangkou reservoir.
Keywords:Morlet wavelet  Danjiangkou reservoir  hydrological year  runoff variation characteristics
