Abstract: | This paper deals with time series of the Yellow River daily
flows at Tongguan hydrological station, from the year 2000 to
2005. Power spectrum analysis and statistical moment scaling
function on a range of scales revealed scaling qualities of the
data. The partition function, which displayed a convex
curvature, and the generalized dimension function showed that
multifractality is presented. The singularity spectrum, which is
single-humped, has shown strong multifractality degree. |
