Annotation:  Changes in the parameters of the ravine network entails a variety of changes in the relief of the territory and relief-forming processes, including changes in surface and subsoil runoff, an increase in the overall division of the territory, an increase in the share of sloping lands. The history of the economic use of the territory determines the features of the erosion process; at present, it is advisable to use historical cartographic materials to study the erosion network. Reliable material of multi-temporal plane surveying in Veselka river basin allows to evaluate and research ravine network development specificities from 1955 to 2017. The research uses modern remote sensing materials and large-scale mid XXth century maps. A ravine network transformation all over the researched area has been identified: ravines changed length, width and shapes of their edges. Some areas appear to form new ravines. Analysis of data of the development of erosion network and the analysis of the spatial distribution of anthropogenic load since the end of the XIX century showed that the increase in the erosion network occurs in the most erosion-unstable areas, one of which is the right tributary of the river Vezelka.
