DYNAMICS OF HAZARDOUS GEOMORPHOLOGIC PROCESSES IN THE CENTRAL PART OF NORTH OSETIA-ALANIA

Abstract

Hazardous geomorphic processes were revealed at the Fiagdon-Terek interfluve on the base of ground aero and cosmic images, fi eld research, and historic data since XVIII century. These results were used for compiling the ecologo-geomorphic maps in the 1 : 200 000 scale. There have been no distinct changes in relief and in the boundaries of the geomorphic processes distribution areas but the Genaldon valley, where in 2002 glacio-rock torrent caused ecological catastrophe. The map of dynamics of hazardous local geomorphic processes was compiled in the same scale. There occur recurrent processes on some local territories and single-shot ones on the others, earlier had not been subjected to such processes. The latter territories tend to stabilize later.
