We examine the time coincidence and spatial homogeneity of the annual stream runoff fluctuations in Siberia and the Far East. A regionalization of the study territory for the time coincidence of the stream runoff fluctuations has been carried out by analyzing the correlation matrix on the basis of the algorithm of automatic classification of objects through identification of groups with homogeneous attributes according to a specified homogeneity criterion. The territory’s spatial homogeneity was assessed by constructing and analyzing spatial correlation functions and accompanied by a checking for the possible anisotropy.
