Kvaterniuk S. Development of scientific bases of multispectral methods and technical means of monitoring of the ecological state of water bodies

This thesis presents the results of research aimed at the development of scientific foundations of multispectral methods and technical means of monitoring the ecological status of water bodies, which take into account the influence of their characteristics on the effectiveness of monitoring the ecological status of water bodies, which is the basis for the effective management of their environmental safety. The method of multispectral ecotoxicity control using an indirect measurement of the concentration of microalgae particles has been developed. A method of multispectral control of pollution of surface waters is proposed, which consists in determining the relative sizes of segments of the surface of the aquatic environment with higher aquatic plants that have morphological changes. According to the results of modeling of light scattering in an aqueous medium, the relative contribution of its layers to the total diffuse reflectance was investigated. Improved multispectral methods for assessing the ecological status of water bodies using phytoplankton. The mathematical model of the process of radiation propagation in aquatic environments with higher aquatic plants, which takes into account the effect of localized absorption, has been improved. The method of multispectral control of pollution of sewage using higher aquatic plants in the treatment complex has been improved. Technical means of multispectral monitoring of parameters of water pollution and the ecological state of water bodies, as well as their software, have been developed. The optimal number of spectral channels and their parameters for means of multispectral monitoring are substantiated. Scientific and methodological recommendations for the implementation of the proposed scientific basis for the use of multispectral methods and environmental monitoring tools have been developed. The results of the dissertation are implemented at Vinnitsa regional water resources management, Olevsky United Territorial Community, private enterprise "Inter-Eco", into the educational process of Vinnitsa National Technical University.
