Introduction. The increasing shortage of water resources in the Republic of Crimea, due to water supplies from the external water source being shut off, emphasized the need to rationally use the existing water resource potential, which in turn requires a balance between the water users’ interests and maintaining a favorable environmental situation in the peninsula’s watercourses. Although in Russian and global practice there is a whole range of approaches to assessing the impact of natural and anthropogenic factors on the state of river geosystems, not all of them are applicable to solving the indicated problem. Methods. By testing integrated techniques, methods and models for assessing the impact of human activity on the stability of river natural and engineering systems (using the Zuya River as an example), we selected the most appropriate approach to develop viable solutions in water management. Results. By comparing the possibilities of using the scoring index method to assess the stability and vulnerability of watercourses to changes in physical and geographical as well as hydrological parameters and water quality, and methodology for the integrated assessment of the geoecological state of water resources of small rivers and the system model “Minor River Basin”, we revealed that only with the use of the latter it is possible not only to assess the real situation but also identify the reasons that impede the rational use of the peninsula’s watercourses. Conclusion. When developing decisions related to water management in the Republic of Crimea, the use of a suitable methodological approach to assessing the impact of natural and anthropogenic factors on the stability of river geosystems will make it possible to avoid mistakes when choosing measures and prioritizing actions aimed at the rational use of the existing water resource potential.

Assessment of the state and rationality of the operation of the water management complex (WMC) of the Poltava region is an extremely relevant study of the present, since the WMC was created in the 60s-70s of the last century and actively provides the sectors of the economy and the population with water resources. The study aim is to assess the water resource potential as the basis for the functioning of the water-chemical complex, to determine the levels of technogenic impact on the water resource potential. A review of the sources was carried out using the Google Scholar database by filtering for the period from 2010 to 2021 and mainly revising publications on numerous samples related to monitoring and control of the state of the water management complex of the Poltava region. According to the official report of 2019, the rivers Dnieper, Psel, Sukhoi Omelnik, Uday received an assessment: slightly polluted waters, the Vorskla and Orzhitsa rivers are moderately polluted waters. The main ingredients responsible for the low water ratings as of 2019 are phosphate ions, manganese, as well as nitrite nitrogen, total iron and BOD5. The manganese content was measured in three rivers, and the average estimate ranged from 5.8 in the Psel River to 11.85 in the Vorskla River. According to the Regional Office of Water Resources in the Poltava region, in 2019, 109.8 million m3 were withdrawn from the natural water bodies of the Poltava region, namely underground water bodies, which is 4.6 million m3 less than in 2018 (or 4.0 %), including 69.83 million m3 (which is 3.29 million m3 or 4.5 % less than in 2018). However, the total water intake in the region over the past 10 years has decreased by 2.2 times. A positive trend is that all discharges occur at treatment facilities of housing and communal services. There is no discharge of return water without treatment into surface water bodies of the Poltava region; however, within the boundaries of settlements there is a discharge of under-treated municipal wastewater and runoff from the urbanized territory. Consequently, balancing water use is possible by introducing waterless, low-water and water-saving technologies in all sectors of the economy, maximum use of water in recycling water supply systems; replacement of physically and morally worn out water supply and water protection equipment, etc.

Abstract The relationship between water abstraction and water availability has turned into a major stress factor in the urban exploitation of water resources. The situation is expected to be sharpened in the future due to the intensity of extreme meteorological phenomena, and socio-economic changes affecting water demand. In the city of Volos, Greece, the number of water counters has been tripled during the last four decades. This study attempts to simulate the city's network, supply system and water demand through a forecasting model. The forecast was examined under several situations, based on climate change and socio-economic observations of the city, using meteorological, water pricing, users' income, level of education, family members, floor and residence size variables. The most interesting outputs are: (a) the impact of each variable in the water consumption and (b) water balance under four management scenarios, indicating the future water management conditions of the broader area, including demand and supply management. The results proved that rational water management can lead to remarkable water conservation. The simulation of real scenarios and future situations in the city's water demand and balance, is the innovative element of the study, making it capable of supporting the local water utility.

The Impact

Due to the fast growth of the economy and population, the water scarcity issue has aroused widespread critical concern. In fact, reasonable structure, adaptive patterns and effective regulation of the economy, society and water resources can bring a harmonious future. Therefore, the study of how to balance economic social growth and water resources is of great importance. A model of the water resource, society and economy system of the Tongzhou district was designed by Stella. The model established here attempts to analyze future trends in social-economic development and the impact of the economic and population growth on water use in the Tongzhou district under three scenarios. The results reveal that the water shortage is very serious. If the current trends persist, the existing water supply will not be able to meet the water demand in the future. Tongzhou district's water shortage will be 162.50 million m3 in 2020 under the business-as-usual scenario. Therefore, it is necessary to develop unconventional water sources and improve the water-saving capacity of production and life to alleviate the water tensions. This research offers insight into larger questions regarding economic growth and water resource management in general.

The paper provides an overview of Russian and foreign articles devoted to the study of the tree litter production and decomposition in forest ecosystems subjected to natural and anthropogenic factors. The spatial variability (below crown and between crown spaces) and the seasonal features of the tree litter production, its chemical composition and decomposition processes are poorly studied. In addition, most of the works, both in native and foreign countries science, highlight the influence of natural factors on the litter production and the processes of its decomposition, while the impact of point sources of industrial air pollution is rarely considered. The study of the variability of the size, fractional and chemical composition and processes of decomposition of tree litter under conditions of industrial air pollution is important for predicting the dynamics of forest ecosystems subjected to the combined action of natural and anthropogenic factors and reducing the negative impact of production processes on forests.
