Abstract
The existence of the Aral Sea depends almost completely on the waters of the Amudarya and Syrdarya rivers, so that a considerable decrease in the flow in the drainage-basin of these rivers results in a lower sea level. As a result huge areas of sea bottom are now revealed, mainly on the eastern sea coast. A significant part of this area is comprised of deposits of a loose mechanical composition, mainly from dust, which is exposed to intensive weathering.Although dust storms in the Aral Sea zone occurred before, the appearance of a new powerful source for salt and dust transport evokes well founded anxiety. This source appeared in a satellite photo in 1975, and the decoded data showed the transportation of salt-dust masses reaching the south and west sea coast. Later investigations show that this source area has a tendency to increase with the formation of a huge zone of moving dust. There is also the problem of the desertification of the Aral east coast.In the world the study of dust aerosol qualities has received great attention, because the deserts which occupy more than 30% of the land area are the main source of dust aerosol. Special attention is given to experimental and theoretical investigations of desert aerosol transport problems for the quantitative description of the wind driven transfer of dust from source to precipitation area.
