Abstract. The study of river basins occupies a special place in the subject of geomorphological works. The basin approach has found wide application not only in geomorphology, but also in related geographical sciences, such as physical and socio-economic geography, geoecology. This is largely due to the possibility of clearly identifying the boundaries of basins, determined by the relief and drawn along the lines of watersheds, in contrast to the boundaries of a transitional nature, often characteristic of natural objects. Scientific interests in the field of river basin research are devoted to both the state of modern physical and geographical conditions in general and changes in individual components, in particular, floodplain forest cover, hydrological and hydrogeological regimes. In addition, important aspects are the rationalization of economic use of the territory of river basins. In this context, the types of anthropogenic impact on the territory are described and the geoecological situation is assessed. In this paper, the analysis of morphometric characteristics of the Buzuluk River basin such as the steepness and exposure of slopes, erosive dissection of the relief was carried out. Measuring these indicators for the selected area is of particular importance in view of the intensive development of agriculture, since all of the listed relief characteristics affect the development of unfavorable erosion processes leading to a decrease in soil fertility. Morphometric analysis was carried out in the QGIS geoinformation system, which allows obtaining updated data and reducing the time of their analysis and interpretation. During the geoinformation analysis, maps of slope steepness, slope exposure and erosive dissection of the relief of the studied territory were constructed. Analysis of the obtained data and natural and climatic conditions allows us to conclude that the conditions are favorable for agricultural activities. Nevertheless, the intensity of economic development requires measures to optimize it to ensure conditions for sustainable development.
Key words: river basin, Buzuluk River, Khoper-Buzuluk Plain, slope steepness, slope exposure, erosive dissection of the relief, geoinformation systems.
