- Аннотация: Abstract . The modern fluvial system on the lowland East European Plain is of depositionaltype. Sediment transport to the seas is only a few percent of the total erosion, and themain part of eroded material is accumulated in the channels. The recent deposition ofsuspended sediments is caused by accelerated soil erosion on the arable slopes, whichled to a high rate of lateral sediment input and deposition at the river headwaters andon the floodplains. The process of accumulation is facilitated by the unfilled “negative”volume of the net of dry valleys formed during the Late Glacial catastrophic erosionevent. Such events of catastrophic erosion of the sediments deposited in the lowlandfluvial systems occur with a frequency of 100-120 thousand years. In the conditions ofboth scarce vegetation and extremal surface runoff, the entire fluvial systems becomethe area of intensive erosion, with the deep incision of gullies and of the river channels.Therefore, despite the modern intensive deposition, delivery ratio for the fluvial systemson this lowland territory is close to one in the long-term perspective.Key words: The fluvial system, delivery ratio, recent accelerated erosion, sedimentdeposition, Late Glacial catastrophic erosion event, East European Plain
