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 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.

Abstract The water resources management model in the state of São Paulo is characterized by the participation of water users from different sectors of the economy within the ambit of River Basin Committees and other organizations of the water management system. The purpose of this article is to present a survey and systematization of the performance of representatives of São Paulo’s agricultural sector in this decentralized and participatory system of water governance. To this end, this article recreates the profile of this sectoral representation in the State Water Resources Council and in the Committees for rural areas with strong agricultural dynamics in the state. The findings of this study reveal significant political and propositional differences between São Paulo’s agriculture and agroindustry sectors. Such differences have to do with the structure and capillarity of the entities that represent these sectors, as well as their divergent concept of management.

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.

Permanent preservation areas contribute significantly to maintaining the quality of water resources and protecting against erosive events. In this sense, this work mains of is to analyze the land use conflict in the permanent preservation areas of the Marapanim River basin, located in the northeast of the State of Pará. To this end, it data were processed using images Landsat of the years of 1988, 1998, 2008 and 2017 to discuss changes in land use for each year. Afterwards, land use was overlapped with the Permanent Preservation Areas of the basin (PPA), to identify the types of use that are interfering in the limits that should be maintained as PPA. The results showed that in three of the four years of analysis, the exposed soil class was present in more than 20% of the inadequate land use in PPA, followed by the Farming class, which increased almost 300% the occupation in PPA in the first to last year of study. Thus, this study can support public policies in order to monitor the sources and margins of water courses for a better management of water resources in this region.

The results of a comprehensive agroecological assessment of the main watercourses of the Zuya river basin are presented. Studies were conducted in 2017–2020 and included: conducting a visual survey, measuring water consumption, assessing the qualitative characteristics of runoff, including phytotesting and determining its suitability for irrigation purposes. It was determined that the main pollutants of the watercourses were sulphates, phosphates, heavy metals. The assessment of salt composition of water resources has shown that they are mostly suitable for irrigation without restriction. However, according to the results of phytotesting, an inhibitory effect was recorded, which indicates a possible decrease in the yield of crops sensitive to water-contained pollutants. The water balance calculations showed the presence of a shortage of water resources in the Zuya river basin. The environmental situation on the surveyed water bodies was identified as unfavorable. The set of priority environmental measures includes: the creation of a permanent monitoring network, the arrangement of settlements with water disposal systems, the inventory of small water storage facilities and the implementation of the required repair and operational work on them, and the optimization of the number of water users.

The De Rossett Farm and Quate Place sites were among the earliest East Texas archaeological sites to be investigated by professional archaeologists at The University of Texas (UT), which began under the direction of Dr. J. E. Pearce between 1918-1920. According to Pearce, UT began work in this part of the state under the auspices of the Bureau of American Ethnology, and that work “had led me to suppose that I should find this part of the State rich in archeological material of a high order.” The two sites were investigated in August 1920. They are on Cobb Creek, a small and eastward-flowing tributary to the Neches River, nor far to the northeast of the town of Frankston, Texas; the sites are across the valley from each other. The De Rossett Farm site is on an upland slope on the north side of the valley, while the Quate Place site is on an upland slope on the south side of the Cobb Creek valley, about 2 km west of the Neches River, and slightly southeast from the De Rossett Farm. Both sites have domestic Caddo archaeological deposits, and there was an ancestral Caddo cemetery of an unknown extent and character at the De Rossett Farm.
