The purpose of this article is to study the processes of water quality management, which are considered as the main factor of the strategic social and economic development of the region and also to form tools supporting this process. The article analyzes the state and development trends of the water sector of the Rostov region from the standpoint of solving the problems of its strategic social and economic development. The authors demonstrate the possibility of intellectualization of regional strategizing processes through the use of water quality monitoring of the knowledge of experts with the use of fuzzy logic. The review of existing approaches to the assessment of water resources quality is given. It is shown that these approaches do not take into account the different requirements of water users to the content of chemicals and compounds in the water but assess the state of water resources in terms of conformity of concentration indices of polluting substances to maximally allowable concentrations. The authors suggest assessing the quality of water resources in compliance with the criteria of the contamination of water resources set for every category of water users. The approach proposed by the authors implies the assessment of water quality in two modes – differentiated and complex. Meanwhile, the suggested tools are universal and can be used in the systems of regional strategizing of the use of various water basins. A conceptual representation of the structure of the management system of water resources quality in the region within the system of regional strategizing is formed and the main problems of its development are identified.

Among the existing state cadastres, an important place belongs to the water, which is the basis of state management of the water fund. According to the Water Code of Ukraine, the water fund includes all water bodies, provides for the systematic determination of reserves and quality of water resources in a particular area.Water quality is affected by a large number of factors, including location, water body category, water intake area, water mirror area, water volume, river network type, terrain parameters and properties, hydrological conditions. No less important is the influence of anthropogenic factors, which is correlated with the degree of development of the territory, land structure, population and settlements, man-made load and so on. The purpose of the work is to analyze the state of watercourses in the Syan river sub-basin and to establish the main factors that affect water quality. The quality of water resources has a great impact on public health, so a careful analysis of the state of natural water sources is one of the important components of the cadastre of water resources. Method. During the research we worked with information provided by the Lviv Hydrometeorological Service, Lviv egional Department of Water Management, research laboratories engaged in monitoring and analysis of water resources of Lviv region for the last ten years, data from the environmental passport of Lviv region for 2020. During processing of results used a combination of methods of system and structural analysis, analytical comparison, mathematical formalization, cartographic materials, which provided the ability to solve problems and achieve the goal and the reliability of conclusions [Sovhira S. V. et al., 2016]. Results. It is established that the water quality in watercourses flowing through the territory that does not carry a man-made load depends mainly on natural factors, namely: territorial location, climatic conditions, relief, hydrogeological and geomorphological conditions, etc. Due to climate change, various natural phenomena and problems with flooding are increasingly occurring, which negatively affect water resources and quality. Floods occur for various reasons and, in recent years, are characteristic of the Syan river sub-basin, especially in mountainous areas. For the territory characterized by high economic development, the water quality of rivers depends: on mining activities; soil pollution; creation and operation of artificial reservoirs; economic activity within the floodplainchannel complexes; dredging and channel-directing works; deforestation and intensive economic activity at watersheds, which is clearly confirmed by the state of water in the Shklo river and its tributaries Gnoyanets, Tereshka, etc. Data on the state of watercourses in the Syan river sub-basin were collected, systematized and analyzed using and adhering to the main provisions of the integrated approach to water resources management according to the basin principle. Scientific novelty and practical significance. It is proposed to use an integrated approach to create water resources management plans based on the basin principle on the example of the Syan river sub-basin. This approach will allow to identify all sources of influence, their nature, relationship and interaction and to fill with official, relevant data geoportal “State Water Cadastre” on the website of the State Water Agency.

The Brazilian Water Resources Policy (Law 9433/1997) establishes participatory and decentralized management, involving civil society, water users and governmental bodies, with the basin committees as the basis of this process. Fifteen years after its implementation, it is possible to perceive accomplishments, but, at the same time, there are some difficulties in regards to the operation of the basin committees in the country. Considering the North Paraíba River Basin – which is completely included in the State of Paraíba, Northeastern Brazil, and presents great social and economic importance for the state – this article analyzes the process of formation, installation and functioning of its Basin Committee (CBH-PB), focusing on its composition, the reasons for the mobilization and demobilization of its members, the intra-relations between segments, and the inter-relations between the CBH-PB and other entities of the State Water Management System (the Water Executive Agency and the State Water Resources Council). The level of decentralization and the quality of participatory management (as it is being performed at the CBH-PB) are discussed and guidelines are suggested in order to allow greater effectiveness to the committee.

The purpose of this study is to survey the thermal regime and eutrophication states in Ilam reservoir in Iran as the case study. For this purpose and to find solutions for improving the water's quality in the reservoir, two general strategies for reducing the entering pollution loads and water depletions from the reservoir's outlets were analyzed by use of the CE-QUAL-W2 model. Results of the simulation of the present situation show the existence of thermal stratification during summer, which results in the qualitative stratification in the reservoir. According to the qualitative criteria, the Ilam reservoir's state is between mesotrophic and eutrophic. Results of the scenarios of reduction of the nutrients show that in the scenario of 50% reduction of the phosphorus and nitrogen loads into the reservoir, the state of the reservoir would recover from eutrophic to semi-eutrophic. Also, release of water from the reservoir during September, October and November would cause the restoration of the quality of water in the reservoir. To avoid the occurrence of critical eutrophication in the reservoir, reducing the ponding time in the reservoir by fast depletion, preventing entrance of the upstream villages' sewage and agricultural drained waters, which are sources of nitrate and phosphate contamination into the rivers, and also management of the usage of agricultural fertilizers have been suggested.

AbstractWater quality studies in Nigeria are usually conducted at local scales and limited to a restricted number of chemical contaminants, while reliable data on trace metal concentrations (including arsenic) are relatively scarce. This study focuses on the quality of available renewable water resources in terms of major ion and trace element concentrations at selected sampling locations in the Lower River Niger basin and part of the Lagos region. A screening of water contamination by arsenic and heavy metals was carried out through water sampling at selected locations using in situ measurement and laboratory testing to estimate heavy metal concentrations and water type. The analysis reveals moderate trace element contamination of the water resources, with the exception of Pb, while Mn and, to a lesser extent, Al exceeded WHO quality standards, but the Arsenic concentrations are within drinking water quality standards and are safe for consumption and irrigation, while the water type is Bicarbonate.

Quality Of Water

The existence of safe and abundant raw water sources is a priceless treasure for any country. Water resources are of particular importance for Montenegro, especially for the development of tourism and agriculture which represent the backbone of its economic development. With respect to water potential, Montenegro is at the top of Europe. However, it is not a sufficient factor, but the very way it is used and protected, as well as the improvement of its valorization. Economic development which is not based on the conservation and good governance of natural resources may have negative consequences for the overall development. The aim of the paper is the study of natural properties of karst ground waters and their changes through interrelation of some ions, as indicators, on the example of five intakes in use. The paper presents the results of the research on the said waters and the values of indicators which point to their exceptional benefits for the water supply. However, the effects of the anthropogenic factor are evident, which are reflected in the range of the mole ratio of Ca /Mg ions ranging from 5.4 to 9.6, and the values (eqv.SO4/Cl) ranging from 0.3 to 2.0. Protection of the environment, especially preservation of the quality of water resources of Montenegro, imposes the urgency of implementation of the objectives of the Water Framework Directive.

Social And Economic Development

Russia today is a dynamically developing state that, despite external pressure, continues to strengthen its positions in the world arena, timely preventing external and internal threats to economic security. Social stability is a fundamental prerequisite for the dynamic development of the state. In this regard, the state's task is to prevent destructive processes in social and economic development, using a set of measures and management procedures. The state of the social sphere, trends and forecasts of its formation have always been in the focus of the interests of the leadership of our country, government organizations and the scientific community. This is because the social sphere is of primary importance for the development of society in particular and the state as a whole. In recent years, large-scale changes have begun to take place in the Russian Federation, including the development of new public legislation, the implementation of targeted projects, the formation of a new concept of public protection of the population, and many actions have been taken to provide a decent level of well-being and increase the quality of life of the Russian people. Despite the fact that the Russian government has made great efforts to reduce the scale of unemployment and poverty, improving the quality of life, the social problem remains quite acute. The main factor was the sudden change in the international situation in the last few years, the introduction of financial and restrictive sanctions, the implementation of hostile political activities by certain foreign states against Russia, and as a result, the complication of the social and financial situation within our state. However, successful social and financial development remains the highest value for the Russian state in the near future. The purpose of this activity is to identify the relevance and complexity of problems of economic security and assess indicators that determine threats to security in the public sphere. Observation and diagnosis of the degree of threats to the national interests of the state on the basis of indicators of socio-economic development indicators in the public domain is a priority task in the existing realities of our life. Modeling the threats to economic security, ie, obtaining specific values of economic security indicators depending on their belonging to a particular risk class (level), it is possible to develop an appropriate plan of measures to improve economic security in the social sphere on the basis of the proposed classification. Monitoring and diagnosing the level of threats to the national interests of the country on the basis of indicators of social and economic development in the social sphere is a paramount task in the existing realities of our life. At the same time, the results obtained serve as a good basis for developing development strategies for the future with the preservation of social stability. The aim of the study is to formulate methodological provisions for the development of the theory of economic security based on the definition of threats to the economic security of the social sphere, using the proposed model of the relationship between the key factors that affect the level of security in this area. The research uses a set of general scientific approaches (abstract-logical, deductive, complex and systemic). The realization of the research process was carried out with the help of the dialectical method of cognition, which predetermines the study of economic phenomena in their interconnection and development. To solve individual problems, economic-statistical methods, comparison methods, absolute, relative and average values, graphical and tabular data representation, correlation-regression analysis, Ward clustering were used.

The results of water quality monitoring of the Saratov reservoir for the period 2000-2016 are presented. Observations were carried out monthly at a stationary station located in the lower tail of the Zhigulevskaya HPP. It is established that the quality of water in the source of water supply is characterized by signifi cant seasonal variability. During the mass development of algae the organic contamination of the reservoir increases and the concentration of nutrients decreases. Excessive content of organic substances in the summer low water complicates the technological processes of water purifi cation. It is concluded that phosphate is the limiting factor restraining the mass development of algae, the concentration of which in the peak of “fl owering” of water is reduced to almost zero.
