Evaluation of the results of monitoring researches of ground waters on the dried part of the Aral sea

Abstract

Irreversible collection of Amudarya and Syrdarya water for irrigation has led to a decrease, and
then to almost complete cessation of the flow of these rivers into the Aral Sea. Violation of the natural
balance of runoff and evaporation, under which the Aral existed, led to the Aral ecological catastrophe
– the death of delta and sea ecosystems and irreversible changes in the natural environment of the Turan
lowland. As the sea level decreases, a new land appears each year, and the one that is located in the rear
part of the dehydration undergoes an extraordinary transformation in extra-arid climatic conditions. The
main natural factor influencing the development and formation of natural complexes on the dried bed of
the Aral Sea is underground groundwater. This affects the structure of the emerging natural complexes or
landscapes that form a number of dynamic regional bands and isolated areas on the dried day.

In the article is given an assessment of the results of groundwater monitoring monitoring of the dried
part of the Aral Sea. Characteristics of the level and hydrochemical regimes of groundwater are given for
three hydrogeological sections: Sudochye-Adzhibay, Muinak and Akkalinsky.
