Abstract
Currently, the qualitative and quantitative hydrological characteristics and the dynamics of their changes are studied mainly for medium and large rivers. The hydrological characteristics of small rivers in Russia are poorly investigated. Considering the increasing deterioration of the ecological state of rivers, affecting primarily the intra-annual water flow distribution of small rivers, the study of flow formation processes, its variability and intra-annual changes is becoming the most important task of hydrology. The article examines changes in the indicators of the intra-annual distribution of runoff of small rivers in the Volga basin based on representative hydrological posts on small rivers in the study area. Water regimes of small rivers before and after the onset of global hydrological changes were analyzed. Spatiotemporal trends of changes in the intra-annual distribution of water flow of small rivers in the Volga River basin were identified. The work presents a first attempt of mapping the trends of changes of the qualitative and quantitative characteristics of water flow of the small rivers.
