The results of using the methodology for monitoring the condition of reclaimed lands disturbed by the construction of the main gas pipeline in the Saratov region are presented. On the basis of a digital elevation model, the lost and renewed volumes of soil were determined, which made it possible to quantify the development of erosion processes at the beginning of construction and installation works and after reclamation. The reason for the intensive development of erosion is revealed - non-compliance with the regulations of departmental rules for laying a gas pipeline through weakly stable soils of underlying rocks. Effective anti-erosion measures (plowing across the slope, installation of drainage shafts and drainage structures at the top of ravines) and a set of remediation work (planning, flattening, fixing the slopes of the ravine with polymer-honeycomb coatings, backfilling them with sand and gravel mixture, sowing perennial grasses) were determined.
