Fractal Dimensional Analysis of Runoff in Jinsha River Basin, China

The hydrological processes are becoming more and more complex. Fractal dimension is one of the important measurements of complexity. This paper utilizes wavelets transform technique to calculate the fractal dimension of runoff for eight stations (Zhimenda, Shigu, Ganzi, Yajiang, Guili, Luning, Xiaodeshi, Pingshan ) in the Jinsha River Basin. The results show: the runoff series in the Jinsha River Basin is fractal; the approach for estimating the fractal dimension by using wavelet transform coefficients is feasible and effective; the fractal dimension of runoff reflect the influence of factors on the runoff.
