Further information


The Dnieper river valley, in spite of being and old one, has only young terraces preserved in the section between Orsha and Shklov: tow Vistulian-Young Pleniglacial terraces and two levels of the Late Glacial-Holocene flood plains. With a large horizontal stability of the channel, the modelling of flood plains resulted only form a vertical accretion of flood sediments. Phases of the intensified activity of the Dnieper which have been identified on the border of the Atlantic and Subboreal and during the Subatlantic about 1000 years BP manifested themselves here by changes of the type of sedimentation on flood plains. These phases are conditioned by the climate, although in the younger one a remarkable influence of human activity is evident.
