The Caspian Sea is the largest closed sea in the world, located on the continent of Eurasia. The coastline is 5970 km, of which 2,220 km is Kazakhstan.
The region of the Caspian Sea adjacent to the shores of Kazakhstan, according to natural conditions, is divided into two parts: the eastern part of the Northern Caspian and the eastern part of the Middle Caspian. The eastern part of the Northern Caspian is shallow with a low coast and low inclines of the bottom. Here the average depth is 2 m, and the maximum depth, in the region of the Ural Furrow, is 8 ... 10 m. The relief of the bottom is complicated by the presence of cans, islands, furrows. It is a semi-enclosed reservoir, a hydrological regime, which is formed in the conditions of the continental and rivers the Urals and the Volga.

It is practically isolated from the direct influence of the waters of the Middle Caspian. The eastern part of the middle is deep-water. The average depth is 200 m, and the maximum depth is up to 700 m.
The Caspian Sea and its catchment area is of great importance for the economies of the Caspian region, including Kazakhstan. This unique reservoir with a diverse flora of fauna and hydrocarbon reserves. Socio-economic development in the coastal zone has a significant impact on the hydrometeorological regime. The level of the Caspian Sea varies considerably during the year
The Caspian Sea hydrometeorological research Department
The main tasks:
• Methodological guidance on the organization and conduct of hydrometeorological monitoring of the Kazakhstan sector of the Caspian Sea.
• Development of methods for sea forecasts and regulatory documents.
• Release of operational sea forecasts and forecasts of sea level fluctuations in the Kazakhstan part of the Caspian Sea and ice conditions on the Caspian Sea.
• Maintenance of a database of operational data on the main hydrometeorological characteristics of the Caspian Sea and the Caspian region.
• Scientific research works on hydro-meteorological survey of the Caspian Sea and the Caspian Sea region.
• Participation in international projects in the Caspian Sea.
The release of operational sea forecasts is one of the main tasks of management. At present this division produces the following types of products:
1. Forecasts of hourly fluctuations in the level of the Caspian Sea in 120 hours in various parts of the Caspian Sea.
2. The Weekly bulletins on the Caspian Sea.
3. The weekly bulletin of wave in the middle part of the Kazakhstan sector of the Caspian Sea.
4. Forecasts of wind and waves for 5 squares of the Caspian Sea in 120 hours (direction and speed of wind, height and direction of waves).
5. Weekly reviews of the ice situation in the Caspian Sea, compiled on the basis of data from Kazakhstan and Russian resources of observations and analysis of space images.
6. Monthly reviews surge phenomena in the Kazakhstan sector of the Caspian Sea.
