Abstract. The territory of the Kumo-Manych depression is located in the fault zone of the tectonic plate and is a characteristic floodplain structure with a large number of swamps, lakes and channels. This territory is characterized by a high anthropogenic load associated with the intensive use of land for agricultural production and, as a consequence, with the manifestations of degradation processes. The relevance of the analysis of the relief of the territory is due to the influence of geomorphological characteristics on the magnitude and dynamics of erosion degradation of land. The methodological basis of the research is the catchment approach, which provides the structuring of landscape structures. The research methodology is based on the use of geoinformation systems for the development of analytical maps based on digital terrain models and geostatistical analysis of the spatial distribution of its structure. The results of the research are presented by analytical maps that allow us to determine the characteristics of the terrain of the terrain with their proximity to a certain location. These results make it possible to assess the erosion hazard of such sites and to develop measures in advance to prevent their degradation. Thus, geoinformation analysis of the relief of the Kumo-Manych depression allowed us to establish that about 47 % of the area of the research site is located in the height range from 20 to 80 m. The steepness of the slopes is insignificant, 52.7 % of the territory has a steepness of less than 1°. Another 38.2 % of the slopes have a steepness of less than 2°. Uncultivated slopes with a steepness of more than 8° occupy less than 1 % of the landfill area.

Key words: relief, geomorphology, geostatistics, elevation ranges, steepness.
