Abstract
A large number of scientific researches have been devoted to the study of the Dniester River Basin, but so far there are no comprehensive studies of the region’s river basin-systems. The intra-annual distribution of river runoff is determined by zonal and azonal factors, and therefore its study includes a comprehensive assessment of the runoff formation. The research was conducted for six left tributaries of the Dniester River (the Zolota Lypa River, the Koropets River, the Strypa River, the Seret River, the Nichlava River, and the Zbruch River) within Ternopil region for the entire available observation period. The calculation of the intra-annual runoff distribution of the Podolia tributaries of the Dniester was made using the real-year model. Three model-years were chosen for the calculation: wet-water year, average-water year, and low-water year. A comparative analysis of the intra-annual runoff distribution in different water periods (low period and wet period) was also carried out. It was established that the intra-annual distribution of the left-bank tributaries of the Dniester River runoff is characterized by a decrease in the spring flood volume and an increase in the summer-autumn and winter low periods runoff volume from the annual between the studied periods, which is caused by modern climate changes.
