Abstract

A series of satellite images taken from 1975 to 1994 provides the opportunity to investigate impacts of sea-level rise and trends of change in the terrain and vegetation of the coastal zone of the northern Caspian Sea. Over this 20 year period, the 2-m rise of sea-level has caused noticeable changes: flooding of the shores, erosion of beach ridges, and a decrease in areas of submergent vegetation. Dynamic elements of coastal vegetation consist of alternating strips of reed, annual saline vegetation, and meadow-solonchak vegetation with tamarisk (Tamarix ramosissima) increasing landward. New vegetation strips have grown up when the old ones die off. Thus, the transgression of the sea has created a return to initial stages of ecological succession in the coastal plain.

The former coastline appears as bands of vegetation offshore; the shape of the new coastline close to the Ural is dominated by dams and levees.
