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.

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.

ABSTRACT Envelope curves are important tools for preliminary evaluation of design floods, for sizing hydraulic structures and for checking the design peak discharge in old dams, to verify their hydrological safety. These curves, associated with a mathematical equation, determine the upper line that involves the maximum values of the floods associated with the respective basin areas. Envelope curves can be global or regional; maybe relative to maximum recorded floods or certain return periods. This paper presents a review of the various envelope curves developed in the world and, in addition, applies them to the hydrological conditions of the watersheds in Ceará. Three envelope curves widely used in the literature were tested. Based on the estimation of new regional parameters for Ceará, envelope curves for floods with Tr equal to 1.000 and 10.000 years were constructed for the State. For developing the envelope curves, 43 hydrological dams’ projects, designed by hydrological techniques adopted by state water resources institutions, were investigated.

Availability Assessment

An update of the State Water Plan is underway in South Carolina. The purpose of the State Water Plan is to develop a water resources policy for South Carolina. A significant portion of the State Water Plan update is to include stakeholders into the planning process. Clemson University continues to facilitate the stakeholder engagement components of the steps to an updated water plan. This research is pertinent to the Groundwater Availability Assessment phase of the State Water Planning process. Overall, stakeholders were interested in all identified groundwater areas of interest in South Carolina. Additionally, they intended to be involved in the entire stakeholder process for groundwater and became more informed on the Groundwater Availability Assessment. Stakeholders agreed that groundwater modeling provided useful information for users in the state and thought the Groundwater Availability Assessment was important for water resources management. Nuances in stakeholder types and registered or permitted users versus nonregistered or nonpermitted users provide important details beyond general results. Moving forward, there are some more mixed results of the stakeholder engagement meetings that are important for planning and decision-making. The groundwater assessment meeting results had general agreement about the appropriateness of the scope, but had less certainty than other questions. Stakeholders generally identified the need for the allocation of additional resources for the planning process. Additionally, mixed results highlight the differences surrounding perceptions of the need for statewide permitting of groundwater resources. This exploratory research is important to water management in South Carolina because it assesses buy-in from those interested in or affected by water resource recommendations forthcoming at the end of the State Water Plan update.

In Brazil, Law No. 9,433/2007 was responsible for establishing the National Water Resources Policy and the National Water Resources Management System, with the aim of maintaining the quality and quantity of water resources, reducing conflicts due to multiple water uses and increasing the participation of civil society in decision-making on issues related to this resource. In 2001, it was the turn of Pará State to institute its own water resources legislation through State Law No. 6,381/2001, in consonance with federal legislation. The main purpose of this study was to analyze the institution of the Water Law in the State of Pará and to investigate how far the State has managed to implement the entities that make up its State Water Resources Management System and its management instruments. For this reason, a documental research was carried out in the record and resolutions of the State Council of Water Resources of Pará, a advisory, normative and deliberative body and occupant of the highest position within the state system, on the SEMAS website that contains in the Management Body of the state's water resources policy and in academic papers related to this subject. The results reveal that, even after almost two decades of this legislation, not all entities in the system are instituted, as well as some management instruments were not elaborated, particularly the State Water Resources Plan given its degree of importance.

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.
