The Atlas of Caspian Sea Hydromorphology
etc.) in the eastern coast of the southern part is connected with the
activity of Submarine mud volcanoes under the seabed. In the eastern
coast, there are big bays such as Krasnovodsk and Turkmen, and the
nearby Agorchin Island. Regarding its geographical position, Caspian
Sea can be considered as the climate index of an extensive part of the earth.
The Caspian Sea water area, with the surface area of 3.5 million km
2
, is
situated within the limit of Azerbaijan, Kazakhstan, Russia, Iran, and
Turkey. More than 130 rivers flow into this sea, among them Volga
River is the first and the most important because of its discharging
regime, and Kura River is in the second place. The coast and seabed
roughness in north Caspian are covered with plain or precaspian land
posts. In this plain, which is called novo Caspian, there are traces of
sedimentary terraces of marine deposits related to various surface
levels of Caspian Sea. The seasonal waterways and rivers which flow
into the Caspian Sea resulted in development of various deltaic
shapes, the best example of which is the Volga river delta. In the
backshore and near shore zone of the north Caspian, the coast has a
gentle slope. One of the important features of the northern coast of
Caspian Sea is the low coastal regions which are sensitive to water
logging cause by storm tide and seawater quick fluctuations. The Da-
gestan coast which is situated in the northeast of Caspian Sea is a nar-
row erosional plain and in its edges the novo Caspian terraces are
observable. In the south of Camur river delta, the coast is step-shaped
and the gravel and sand alleviate sediments are observable on the
terraces.
The coastal structure of Kizlar region is very interesting. In this place,
the great Caucasus Mountains end in Caspian Sea, and as a result the
