Abstract:This paper was mainly focused on analyzing the trend and the change point in hydrological time series by using the resampling methods.In order to satisfy the characteristics of auto correction,a moving blocks bootstrap was used to analyze the hydrological time series with the conventional trend and change point analysis methods,i.e.,the t test,the Mann-Kendall test,the Spearman's rho test and the median test for trend,and the runs test,the Mann-Whitney test,the cumulative sum test and the deviation test for change point detection.With the Yellow River as a case study,it's shown that the resampling methods are very valuable for the time series analysis.
