Abstract

The hydrological zoning of the Ural River basin has been clarified in terms of synchronism and in-phase fluctuations in annual runoff. 5 hydrological regions have been identified. For 9 hydrological posts and 5 meteorological stations located in different parts of the basin, a detailed statistical analysis of long-term data was carried out. A single 1975 year of the beginning of hydro-meteorological changes in the basin was revealed. For each hydrological region, statistically significant changes in the annual and seasonal runoff were revealed. The assessment of the factors of change in runoff was carried out. Areas with a predominant influence on the change in runoff or anthropogenic load on water resources or climatic changes are identified.
