The article presents a comprehensive scientific analysis of the spatial structure, morphometric characteristics, and current state of the river network of the Middle Dnipro sub-basin within Left-Bank Ukraine. The study focuses on five major basins of the left-bank tributaries of the Dnipro River — the Trubizh, Supii, Sula, Psel, and Vorskla rivers — which determine the hydrological regime of a significant part of the region.
The authors employed an integrated methodology combining historical and cartographic analysis, Earth observation (EO) data, and modern geographic information system (GIS) technologies, particularly QGIS. This approach made it possible to уточнити the quantitative and qualitative parameters of the river systems within the study area.
The study identifies and systematizes the patterns of river network formation resulting from the interaction of natural factors, including tectonic structure and paleogeographic conditions. Particular attention is given to assessing the extent of anthropogenic transformation of river channels and their morphometric parameters caused by human activities, including drainage reclamation and channel straightening.
A detailed morphometric characterization of each river system is provided, including basin area, length of the main rivers, types of river systems, and their configuration features. In addition to the major rivers, the structure of their tributaries — numerous small rivers and streams forming an integrated regional hydrological system — is also analyzed.
The results provide a fundamental basis for further monitoring of the ecological condition of water resources, forecasting their changes under current climate challenges, and developing strategies for sustainable water management within the left-bank part of the Middle Dnipro sub-basin.
Key words: river network, Middle Dnipro basin, left-bank tributaries of the Dnipro River, river basin morphometry, cartographic modeling, Poltava Region, Left-Bank Ukraine.
