Assessment of hydrogeoecological features of the Yesil River Basin

Abstract

Aim: The aim of the present study was to examine the hydrochemical composition and geoecological features and to assess the level and nature of anthropogenic pollution in the Yesil river basin. Methodology : Field studies are an integral part of observation and analysis of landscape components. Sample analysis of chemical composition of the Yesil river basin water was conducted in July-August 2016 to ascertain the current state of geo-environmental pollution of the basin water. Results: Reduction of river water causes sharp deterioration in the sanitary condition of river. Great harm is caused by pollution by industrial, agricultural, municipal and domestic sewage. However, there is an increased content of SO4, NO, and NO2, Fe and total salinity of water. Interpretation: Systematic analysis of water quality in the Yesil indicates that the river copes with pollution mainly by the self-cleaning processes. Comparative analysis of qualitative and quantitative indicators of the Yesil river basin water surface indicates the presence of some of their relationship. The solution to the problem of stabilization and improvement of the ecological state of the Yesil river basin geosystems, under intensive anthropogenic impact, requires maximum consideration of the specific nature condition and the analysis of key factors and processes that affect its condition.
