Abstract

Studies of risks remain among the most claimed issues of geology and geomorphology. The system-morphological approach developed by A.N. Lastochkin provides a new promising basis for this. We studied slopes of the ridge Aibga, Western Caucasus, to assess geomorphlogical risks in the area of construction of the mounting ski facilities for Winter Olympics, 2014. The first step of study is a compilation of an analytical map, which covers all morphological elements of the area. Then we studied current geologic and geomorphological processes and estimated risks associated with them. The last step is the assessment of risks related to certain characteristics of exposed rocks and to possible tectonic movements. These morphological, geological and engineering parameters are combined within an integrated score of geomorphological risks, which is presented on the appropriate map.

Keywords

System-morphological approach, geomorphic risks, geohazards, assessment, mapping, Aibga Ridge.
