Abstract
Anthropogenic mudflow landscape in the Teberda river valley and avalanche-mudflow landscape of the Gonachkhira river valley are described. Mudflow activity at both sites depends mainly on summer cyclones, carrying warmth and precipitation. This influence is especially strong in Gonachkhira valley, where precipitation is heavier. Rapid and different changes are characteristic to landscape of this site. Large mudflow took place in 2004, several micro-mudflows in 2008, and avalanches in 2009-2010. These events each time changed young small forest composition and cover sediment layer.
Mudflows in the Lower Teberda site occur on the surface dump of old coalpit. This highly erodible ground undergone heavy washout by melt, rain, and mine water. Rapid alternation of erosion and accumulation lead to high changeability of micro- and mesorelief.
