Published 19.03.2021 130 large and small rivers flow into the Caspian Sea. Nine of them have a deltoid mouth. Among the largest rivers are the Volga, Ural, Terek, Samur, Sulak, Kura, and Atrek. The largest river that flows into the reservoir is the Volga. During the year, an average of 215-224 km3 of water flows out of it. All of the above rivers replenish the annual water supply of the Caspian Sea by 88-90%. On average, RSE "Kazhydromet" makes a weekly forecast of the level of the Caspian Sea. In the Caspian Sea, the sea level fluctuation is expected to be around minus 28.36 m, with a rise to a maximum of minus 28.07 m and a decline to a minimum of minus 28.80 m.
* The calculated characteristics were obtained using the MIKE 21 hydrodynamic module of the Danish Hydraulic Institute, adapted in the RSE "Kazhydromet" to the conditions of the Caspian Sea. The calculation used data from sea level observations and a numerical forecast of the baric field for 24-120 hours.
The actual state of the water surface of the Caspian Sea for the period from March 11-17, 2021 corresponds to the previous weekly forecast. The visual coastline of the largest closed reservoir is shown in the satellite image for March 15, 2021. A snapshot of the NASA project.
