Time-Series Characteristic Analysis of Groundwater Level Based on Fractal Theory
Xia Wu · Journal of Irrigation and Drainage · 2012
The time-series characteristic of groundwater level was analyzed using R/S analysis and qth-order moment structure partition function in Liuyuankou Irrigation System.The research results indicated that the time-series of groundwater level had fractal property.Fractal dimension ranged from 1.054 to 1.311.The time-series of groundwater level had long-range correlation and was more sensitive to initial condition.It also indicated that the time-series had multi-fractal characteristic,but the property was not obvious.
