- Аннотация: The sedimentation rates in lakes of the Caucasus in the Late Holocene are estimated on the basisof radioisotopic dating. The lakes are located in different height zones. The columns of lake sediments weresampled at areas with maximum depths. The contribution of sediments to the lakes and the sedimentationrates and their changes mostly depend on natural factors due to the minimum human impact on the watersheds of the lakes studied. It is found that the sedimentation rates in alpine Donguz-Orun Lake haveincreased (0.32 cm/year over last 30 years). A decreasing sedimentation rate is determined for the alpineGarabashi Lake, the catchment area of which contains no glaciers and has a high projective grass cover. Thesedimentation rates of two mid-mountain lakes with grassed and forest drainage areas are 0.05–0.07 cm/year,and almost half of sediments belong to organic relics. The sedimentation rates of low-mountain SukhoiLiman Lake are 0.1 cm/year with a slight increase, which is related to the enhanced anthropogenic impact.
