The Analysis of the Characteristics of Annual Runoff Series through Wavelet Coefficients

Article Preview

Abstract:

A runoff-sequence contains many frequencies, from the point of the wavelet transfor- mation, they are included in different wavelet coefficients. Therefore, when a smooth wavelet function is used, changes in multi-time scale and jump characteristics of precipitation time series have been probed the tendency. Wavelet transform can clearly demonstrate all kinds of characteristics of precipitation runoff series: the strength and distribution of time scales. The monthly data used in this paper comes from Guidei hydrology station of Yellow River (1919-1994) and Yichang hydrology station of Yangtze River (1946-1976), and the yearly ones from Yichang hydrology station (1882-1984).
