Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The study provides the results of modern state and the causes for thetransformation of aquatic ecosystems of Ile river delta in the period from1995 to 2015 years based on the data of water availability dynamics andhydrological regime of the Ile and study of multi-satellite images of theregion. Analysis of satellite images of the delta area in varying resolutionrevealed adjustment in hydrographic network of branches, channels andlakes of the Ile delta. Downward trend in area and drying ducts and lakesin the three main systems of the Ile delta (Topar, Ile and Zhideli) are shown.Key words: hydrographic network, the Ile river delta, streams, lakes,lake system, aquatic ecosystem, GIS technology, remote sensing methods
