Purpose: to predict and prevent the destructive consequences of dangerous exogenous geological landslide and mudflow processes.
Materials and methods. The studies were carried out according to the methods set out in SP 11-105-97 (part 2), using geodetic measurements and instrumental geotechnical monitoring.
Results and discussion. The contribution of erosion processes to emergency incidents is substantiated. On the example of an alpine climatic complex, the interdependence is described, namely: upon a detailed examination of the mudflow channels, the accumulation of loose clastic material was found, which indicates landslide, debris or scree formation centers. Here, the active zone of landslide impact is 35–40 m long and 35–37 m wide. Mudflow processes also regularly occur in the basins of the Sulimovsky, Shumikhinsky and Rzhanoi streams. The formation zones of such dangerous geological processes as landslides and mudflows are identified at the plotin gradations of 0–17°, subject to minimal formation in the intervals of 0–17° and more than 55°.
Conclusions. In order to predict and prevent the destructive consequences of dangerous exogenous geological processes, it is recommended: carrying out instrumental geotechnical monitoring with the mandatory inclusion of geological research; arranging drainage and water diversion systems with their regular maintenance (cleaning, repairs); timely maintenance and, if necessary, reconstruction of protective engineering structures; arrangement of anti-erosion protection on unforested slopes using geomats, anchor fields or other methods of strengthening slopes.
