Based on observations in Jiangjia Gully, the authors focus on the integrity of surge sequence by considering the autocorrelation and tempo-spatial interval. The Hurst exponent is employed to express the autocorrelation. The results show that the Hurst exponents are exclusively bigger than 0. 5, the value for random series without long-run aftereffects, suggesting the long-range correlation of the surge sequences. Furthermore, an event-space is introduced by taking each surge as a point assigned with a parameter set.
