Integrated water resources monitoring system within the structure of environmental safety in southern Ukraine

Purpose. To substantiate the components of monitoring of resource-saving regulation of the water regime of river basins in the system of environmental safety of the southern regions of Ukraine on the basis of managed restoration of water resources and elements of the disturbed aquatic environment. Methodology. A complex of standardized methods of field, desk and laboratory research, as well as methods of statistical processing of experimental data using the method of central composite orthogonal planning was used. Findings. The paper analyzes the trends in the water cycle in technological complexes and agricultural complexes with the subsequent use of local measures to condition the resource in order to recharge the water supply source. The modes of operation of technological equipment using process and recycled water in traditional and energy-saving modes were modeled. Schemes of recycled water purification for use in the technology park were developed to reduce the cost of the production product. A study of drought processes in the agricultural sector in the southern region was carried out to reduce the risks of water management with renewable resources. Experiments on the absorption of various types of anthropogenic mixtures through porous artificial and soil structures were performed in the field, followed by the determination of background concentrations of pollutants. Originality. During field and laboratory studies, applied tools for regulating the nutrition of water basins were developed. For the first time, a system for identifying agronomic drought phenomena and selecting priority measures to minimize the impact of moisture deficit in the context of global warming on the regional economy was designed. Greening of recreational areas of technology parks for the separation of sediment during gray water restoration was carried out. Recommendations were developed to regulate the operation of water management areas of enterprises in conditions of fluctuation in the flow of recycled water and other auxiliary economic needs to increase the water use coefficient of cities. Methods of wastewater treatment for the formation of components of water basin recharge were systematized. To improve the aquatic environment, a number of water protection concepts and programs have been developed, such as supply management, demand management, and integrated water resources management and environmental safety measures. Practical value. A system of combined nutrition of the water regime of the reservoir basin has been developed. Methodologies for the recovery of recycled water from municipal and industrial enterprises for reservoir nutrition were calculated and tested. Operating modes of the cavitation unit for surface water recovery were established. The directions of development of the water basin in the context of global warming and the anthropogenic load of cities have been developed.
