Pochaievets O. Spatio-temporal dynamics of the minimum flow of the Tisza River basins within Ukraine.

The dissertation is devoted to the study of spatiotemporal dynamics of the minimum water runoff of the Tisza River basins within Ukraine. When considering the problems of the minimum runoff studies, it was found that there are considerable differences in the approaches to the establishment of the minimum runoff periods and the fundamental estimated values of both domestic and foreign scientists. It is established that an essential condition for the estimation of the minimum runoff of water, especially in mountainous regions, is the consideration of the genetic features of the formation of the minimum runoff, namely the estimation of the minimum costs of summer-autumn and winter borders. It is revealed that the determining factors that influence the formation of the minimum flow of rivers of the Tisza River basin include climatic conditions, geological structure, hydrogeological conditions, soils, vegetation and economic activity.
