ANALYSIS OF THE STATE OF STUDY OF THE RIVERS OF THE DNIESTER BASIN IN TERNOPIL REGION

The purpose of the study is to analyze the study of the river basin systems of the left tributaries of the Dniester, located within the Ternopil region of Ukraine. Information is provided regarding previously made generalizations regarding the study of the rivers of the basin from the works of the 19th century. to modern monographic publications and individual articles. The study of the first publications summarizing the regime of the rivers of the basin and their use shows that it was the needs of shipping that determined the beginning (in the middle of the 19th century) of regular observations of water levels on the Dniester, when the first four water measuring posts were opened. The first water measuring posts on the left-bank tributaries of the Dniester within the region were opened during the times of Austria-Hungary – in the 80s and 90s of the 19th century. Measurement of water consumption at individual stations began at the beginning of the 20th century. Since the end of the 80s of the last century, the number of posts on the Podil tributaries of the Dniester within Ternopil Oblast has remained unchanged and amounts to 11 units. A significant drawback of stationary hydrometric observations within the basin for the period from their beginning to the middle of the 20th century. there is an interruption in the series of observations at almost all posts, since a significant part of the materials of observations at posts that worked within the boundaries of the former Austro-Hungarian (before the First World War), Polish and Romanian parts of the basin in the interwar period (20-30s of the XX century. ) turned out to be lost. The analysis of the state of study of the rivers of the region and their basins shows that the greatest attention in the works of domestic scientists is devoted to the analysis of various aspects of the hydrological regime of the rivers of the region. Research on the hydrochemical regime and water quality, the hydroecological component, attracted much less attention.
