Ecological Monitoring Of Small Water Systems: Algorithm, Software Package, The Results Of Application To The Uzh River Basin (Ukraine)

Abstract

A systematic approach to environmental monitoring of small water systems and its optimization is proposed. For simplify the storage of large amounts of information, accelerate the obtaining of preliminary conclusions of water resources condition, predict the dynamics of both individual indicators and their system attributes, and develop a user-friendly interface, which is tied to the area. To carry out the research, samples of water were taken near the corresponding sections of industrial enterprises of Korosten region, as well as discharges of a storm water system. Based on the standard approach, with the help of physicochemical methods of analysis practically all the hydrochemical parameters in the studied water body were determined. The obtained results were compared with the regulatory guidelines. For systematization and maintenance of environmental monitoring, a software package has been developed, which has been tested on the results of the instrumental laboratory analysis of surface water quality of the river Uzh. The software package is developed to establish local sources of pollution, monitor potentially dangerous man-made objects, and better manage of water resources. A user-friendly interface has been developed, which is tied to the area and is easily adapted to other monitoring objects. Thanks to the developed software package, the implementation of an integrated approach to the collection and analysis of monitoring data is carried out quickly, efficiently and conveniently. The developed approach allows easy adaptation to the objects of the research and does not require significant capital investment.

Perspectives of nuclear energy development in Ukraine on the global trends basis

“…We analyzed the websites of international organizations dealing with nuclear energy issues and scientific literature during working on this research. Functioning of nuclear fuel cycle facilities are considered in publications [1,2,4,[15][16][17][18], issue of developing mathematical and software tools for assessing the impact t of energy facilities on the environment is considered in works [19][20][21][22][23][24][25][26][27][28][29][30][31]. Specifics implementing of alternative and renewable energy sources are described in publications [32][33][34][35][36][37][38][39][40].…”

The Ecological Assessment of Small Rivers in Ukraine Under Conditions of Intensive War Impact

“…Due to the small catchment areas, they are the most vulnerable to destructive anthropogenic influence, so they require a constant monitoring of water quality. And, in cases of significant pollution, they require expensive methods of water purification (Tarasevich et al, 2008;Kotsiuba et al, 2019).…”

Quantitative assessment of water quality in the Vidsichne reservoir (Zhytomyr, Ukraine)

“…The available numerous methods and techniques are directly or indirectly based on the transformation of quantitative indicators into qualitative indices of the ecological state. According to the analysis of numerous studies, the objective assessment of the ecological state of water bodies is based on the combined use of hydrochemical and hydrobiological data [1][2][3]. As part of the standard approach, the indicators determined at individual points of the water body are compared with the normative values of the corresponding indicators [4][5][6].…”
