Визначення екологічного ризику погіршення стану водотоків басейну річки Уди

Abstract

We presented new method for assessment of the environmental risk of deterioration of a surface water state. A base of the methodology for assessment of the risk of water ecosystem well-being disruption is the determination of all parameters of the state of quality of surface waters that exceed the ecological standards using the probit-regression model. The process of determining ecological risk for watercourses of the Udy river basin in Kharkiv region showed a high level of danger to the well-being of the water ecosystem. Ranking of the observation posts for the quality status of the Udy river in terms of the ecological risk makes it possible to identify the most polluted watercourses. Proposals for implementation of environmental measures based on the analysis of water use efficiency, taking into consideration landscape and ecological features of a catchment area
