But the large-scale avalanche hazard zoning is not yet used for the land use planning in the country. In this research, the importance of the avalanche hazard zoning implementation in Russian practice is discussed on the example of Krasnaya Polyana, Sochi (West Caucasus). We applied internationally accepted avalanche hazard zoning approach for “Gorky Gorod” mountain resort. Using GIS technologies in combination with DEM and remote sensing as well as data of field observations, 87 potential avalanche release zones have been indicated. Numerical simulations of avalanches using avalanche dynamics program RAMMS were performed for understanding the avalanches dynamics and to determine the avalanche runout distances and impact pressures. The numerical simulation results were applied as a basis for the avalanche hazard zoning. First, we applied Swiss avalanche hazard zoning approach when avalanche hazard zones were indicated according to avalanches return period and impact pressures. Second, we considered the avalanches impact pressure values in relation to their destructive effect and present the obtained results as a map. The developed avalanche hazard zoning maps were analyzed in respect to already constructed infrastructure and organized avalanche protection measures.
