Hydrological and morhgological processes at the Volga mouth area and their response to the Caspian Sea level fluctuations

Abstract

Investigations in the Volga delta morphology and regime revealed principal characteristics of the dynamics of the delta surface, its coastline and bottom morphology, as well as channel network on the delta; changes in water and sediments distribution between delta branches, water level fluctuations -both within the delta and offshore, and water and 'sediment flows dynamics. The processes are shown to be considerably influenced by the changes in the Caspian Sea level.
