The Caspian Sea is the world's largest enclosed body of water located on the Eurasia. The coastline is 5,970 km, of which 2,320 km belong to Kazakhstan.
The region of the Caspian Sea adjacent to the shores of Kazakhstan is naturally divided into two parts: the eastern part of the North Caspian and the eastern part of the Middle Caspian. The eastern part of the North Caspian is shallow with a low coast and small slopes of the bottom. Here the average depth is 2 m, and the maximum, in the region of the Ural Furrow, is 8...10 m. The bottom relief is complicated by the presence of cans, islands, grooves. It is a semi-closed body of water, the hydrological regime of which is formed in a continental, arid climate and is determined by the runoff of the Ural and Volga rivers. It is practically isolated from the direct influence of the waters of the Middle Caspian. The eastern part of the middle is deepwater. The average depth is 200 m and the maximum is up to 700 m.
The Caspian Sea and its watershed are of great importance for the economies of the countries of the Caspian region, including Kazakhstan. This is a unique reservoir with diverse flora and fauna in the bowels of which significant hydrocarbon reserves are concentrated. The socio-economic development in the coastal zone is significantly affected by the hydrometeorological regime of the sea and the coastal territory, and above all, the position of the sea level surface.
Water level of the Caspian Sea, as a closed body of water, in contrast to sea level fluctuations, is subject to significant long-term, interannual and seasonal fluctuations.
Department of Hydrometeorological Research of the Caspian Sea
The main tasks are:
Calculation of surface level and wind currents is carried out using Danish technology MIKE 21, adapted to the conditions of the Caspian Sea, based on numerical forecasts of wind fields and atmospheric pressure obtained in accordance with the license agreement with the European Center for Medium-Range Weather Forecasts (Great Britain), as well as information coming from Kazakhstan stations and posts and stations of interstate exchange.
Predictions of the wave environment are made using the statistical method of predicting the waves, as well as based on the wave spectral model SWAN, adapted to the conditions of the Caspian Sea. The wind field data from the European Center for Medium-Range Weather Forecasts with a grid pitch of 0.25 ° to 0.25 ° are used as input parameters.
The forecast of driving-surge situations is based on the developed hazard criteria.
Studies of the hydrometeorological regime are carried out using traditional statistical and hydrological methods.
The number of forecasting points and their location may vary at the request of the customer.
The management staff has many years of experience in interdisciplinary research on the Caspian problem, including electronic mapping, hydrometeorological surveys, modeling the processes of unrest and flooding of the Caspian Sea coast. Specialists underwent an internship at the Danish Hydraulic Institute for monitoring and modeling of hydrodynamic processes and improved their qualifications in the training centers of WMO, UNESCO, IOC and others. The department has a specialist with a PhD degree, two specialists are trained in doctoral studies at the Russian State Medical University (St. Petersburg, Russia) and KazNU named after Al-Farabi (Almaty, Kazakhstan). The department is headed by a candidate of geographical sciences with a degree in Geoecology.
