Abstract

More than half a century has passed since the Volgograd reservoir creation. During this period a new coastline was formed: its extension within the Volgograd region on the right high bank has increased by 12% due to the large Balaklejka River creek, and on the Eastern bank it has increased by 40% due to the formation of huge bay-estuary of the Yeryslan River; though the small rivers’ bays were mostly silted up and pinched; abrasion coasts were formed and retreated only to a few meters. No increasing of landslide and erosion processes are noted upslope.

Abrasion-accumulative coasts were formed along the Eastern lowland bank. Their retreat reached hundreds of meters (up to 200 meters), but the forecast given 50 years ago generally proved himself, and settlements, that were moved from the flooded area, have not suffered.

But the stabilization of coastal processes did not occurred due to the reservoir “drawdown” or overflow with amplitude up to 2–3 m. Thus, the further evolution of the Volgograd reservoir coastal zone now represents the evolution of anthropogenic and natural system, which functioning depends on the management.
