The article analyzes the negative impact of enterprises and public utilities on the surface water quality of the Western Bug River basin (within the Lviv region). The dynamics of changes of indicators of the main pollutants at six control points (2016-2018) and the assessment of surface water quality for 2018 are presented. It is proposed to replace the control units on the Western Bug River and its tributaries in order to obtain more accurate information and improve the work on the basin water management.
The linear dependence of some geological (significant) factors responsible for landslide and flooding processes on the cost of geotechnical surveys determining these factors was proved. The principle of selection of engineering-geological surveys, which assess the factors of occurrence of landslide and flooding with high probability, was developed. The possibility of identifying economic territories that may be susceptible to landslide and flooding processes based on already existing basic data of previously conducted engineering-geological surveys is substantiated. A preproject (planned) method of calculating the costs of geotechnical surveys based on the existing basic data is proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
