Current state and the reasons for the transformation of aquatic ecosystems of the Ile river delta
Abstract
The study provides the results of modern state and the causes for the
transformation of aquatic ecosystems of Ile river delta in the period from
1995 to 2015 years based on the data of water availability dynamics and
hydrological regime of the Ile and study of multi-satellite images of the
region. Analysis of satellite images of the delta area in varying resolution
revealed adjustment in hydrographic network of branches, channels and
lakes of the Ile delta. Downward trend in area and drying ducts and lakes
in the three main systems of the Ile delta (Topar, Ile and Zhideli) are shown.
