Abstract

The Caspian is the largest endorheic lake on Earth, situated on the boundary of Europe and Asia, yet it is called a sea due to its sheer size and its seabed that has been formed by oceanic Earth crust. The Caspian Sea has a fluctuating hydrologic regime that causes both sharp drops and sudden increases in its water level. The present article examines the specifics of the relief of the sea floor in the Kazakhstan section of the Northern Caspian which is the most susceptible to underflooding (due to a rise in the water table) during water surges. This article analyses the dynamics of the fluctuating water levels in the Caspian Sea during the period of decreased and increased water levels from 1960 to 2013. It also offers the possible reasons for these changes in the water levels of the Caspian Sea.
