Determination of the Ecological Risk of Deterioration in the Water Flow of the Udy River Basin ofKharkiv Region, Ukraine

Abstract

The new method for assessment of the ecological risk of deterioration of a surface waters condition was presented. The methodology for assessment of the risk of the water ecosystem wellbeing disruption is based on 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 the 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 river sections.
