Project summary

The desiccation of Aral Sea has caused the fast developing processes of desertification and degradation of fertile soils on enormous elbowrooms of Central Asia around of Aral Sea. The area of water surface was reduced on 40%, and volume of water mass was reduced on more then 2/3, it also has changed the water saline composition. The Aral water area has disintegrated on several separate basins. Because of airing processes development on sand-saline deposits of dried-up bottom of the Aral Sea arise the sand-saline storms, which carrying around the great mass of dust-saline particles to the hundreds km, that causes the salinization and degradation of fertile soils. All of these processes can be described mathematically as the system of partial differential equations with initial and boundary conditions. On the base of this description it is possible to build the identical mathematical models, which, in turn, can be simulated on the computer.

The goal of the project is the elaboration and numerical computer simulation of the aerohydrodynamic models of the following environment problems of Aral Sea Basin:


· transportation and distribution of the salt particles from the Aral dried-up bottom with accounting the climatic, meteorological and topographical conditions;
· hydrodynamics of water basins of Aral water area;
· dynamics of local and global meteorological features of Aral region.

The results, which will be presented at the form of numerical methods, computer programs packages, article and reports, published in seal, as well as in Internet on the special Web-site can become a strict scientific base for elaboration the plan of sustainable development of the Aral Sea region.

The Project Participants are high-qualified specialists on computing aerohydrodynamics, computer and internet technologies. Some time ago (up to 1991) they were occupied by the problems of aerodynamics of high-altitude flying apparatus (weapon transit facilities), have strong experience on computer simulation of the ecological problems of water and air environment, including the environment of Aral Sea Basin.
