Effect of debris flow activity on the landscapes of the Greater Caucasus
Debris flow activity in the mountains of Western and Central Caucasus and its effect on landscape structure were investigated on the basis of long-term observations, interpretation of remote sensing data, phytoindication and lichenometry. Intensification of landscape changes in recent decades due to debris flows was detected. It was found that several debris flows were initiated by snowavalanche releases in the places where they were not observed for the past 40-50 years if ever. Four main types of debris flow fans dividing into several subtypes were distinguished according to the characteristics of landscape structure and dynamics. Some common and individual features of vegetation and soil successions on newdebris deposits in different altitudinal belts were determined. Large-scale landscape maps for zones affected by debris flows were compiled.
