Spatiotemporal Patterns of Long-Term River Runoff Dynamics in the Ural River Basin

The article presents the results of the analysis of spatiotemporal patterns of long-term river runoff dynamics in the Ural River basin. We note the absence of statistically significant or unidirectional trends, due to the transformations of the intra-annual runoff distribution within the basin under study. Climate-induced changes in the river water availability are confirmed by the in-phase character of runoff fluctuations in most rivers of the Ural River basin. Five phases of runoff change have been distinguished in the study basin for 1938–2022, characterized by different duration and intensity.
