- Abstract:
-
Based on the data of annual runoff from 1956 to 2010 of the Kaidu river, the characteristics of annual runoff variation trends was researched by the method of wavelet analysis,and the periodicity and mutability were discussed, the wavelet transform analysis was jointly adopted to unravel characteristics of runoff variations of the Kaidu River. Results of wavelet analysis show that annual runoff at two stations generally presented an increasing and a decreasing trend, the change rates were 1.382 m3/s and -0.113 m3/s, respectively. Annual distributions were mainly concentrated in June to Augest; the biggest monthly runoff at Dashankou and Yanqi station both occurred in July. The runoff in 11~17 a oscillation period was most notable and it was relatively notable in 20~30 a period. Principal periods of annual runoff at the Dashankou and Yanqi stations were found to be 27 a, and the secondary periods were 16 a.
