Autorun analysis of hydrologic time series

Abstract

Abstract A new methodology which is referred to as the “autorun analysis” has been developed to investigate the sequential properties of a hydrologic time series. The relevance of the methodology as a potential tool in water-engineering applications as well as in statistics, is due to its distribution-free behaviour. The autorun analysis yields the same results as those of the autocorrelation analysis in the case of normally distributed random variables only. An application of the autorun analysis to some mean annual flow series has been performed.
