Morphology and dynamics of Volga-Akhtuba flood plain

Abstract

The Volga-Akhtuba Hood plain is the area of long-term constant accumulation. In the result of multiannual positive balance of deposits the rise of the river bed takes place as well as growth of valley altitudes. The superimposed flood plain and regressive growth of islands are the evidences of recent accumulation. Paleogeomorphological analysis leads to conclusion that Volga channel is moving to the right flange of the valley. Comparison of ancient and recent channel forms reveals the more water content of Akhtuba at early stages of Chanel formation.
