Geologic-geomorphologic structure and development of Berestovaya ravine (Rostov region) during Holocene

Abstract

The ravine was thoroughly investigated by means of geologic and topographic-geodetic methods. Three episodes of filling of the ravine by slope deposits during Boreal and Early Atlantic periods of the Holocene were revealed. Two latest were correlated with linear erosion animation as the result of fires. Active secondary bottom erosion occurs during only few last centuries b.p. The longitudinal profile of the ravine was reconstructed, volumes of accumulated material and eroded one were calculated. On this account the conclusion was made that accumulation in Holocene overbalanced bottom erosion.
