abstract: The work presents research results on the acquisition and processing of spatial data, application of spatial analyses and modeling for the purpose of precisely determining the location and extent of anti-erosion meliorations. A Digital Watershed Model (DWM) has been build through digitalization of analogue maps. The DWM was a basis for further investigations, including the arrangement of rural roads in the relief of the terrain, the urgency of road hardening and qualitative water erosion indicators. Moreover, the SINMAP model was used for modeling slope stability, and the EROSION 3D for modeling water erosion. The results provided a basis for the preparation of a map of recommended anti-erosion measures, taking into account the urgency of their implementation.
