Water resource management: a comparative evaluation of Brazil, Rio de Janeiro, the European Union, and Portugal.

This paper presents an overview of water resource management in Brazil, in particular the state of Rio de Janeiro, and in the European Union, with an emphasis on member country Portugal. The study examines the primary laws, governing bodies and water resource plans. The paper describes the concerns and interests of the scientific community and other sectors of society with regard to water resource management. The paper also draws attention to challenges and opportunities concerning the main objective of water resource management, which is to ensure the availability of water of high quality and sustainable quantity. Additionally, it also mentions good and poor management practices. Among the concerns highlighted are integrated water resource management and water resource monitoring. The objective of this study was to contribute to water resource management processes. The primary reasons for this study are the growing scarcity of freshwater in the world, recurrent problems in managing this resource and a desire to contribute to the improvement of the current situation. The study of water management in different contexts allows for a greater understanding of the subject, thereby assisting the decision-making of managers and society in general with regard to environmental quality and ecological and human health. There is an increasing interest in efficient water resource management, which creates a demand for information on the subject. Both Brazil and the European Union are facing problems related to quantity and quality of water. Problems like scarcity of freshwater, contamination, salinization, and floods. This makes the realities of them quite close, despite the physical distance between them. In general, Brazil, Rio de Janeiro, the European Union and Portugal have similar water resource management requirements. If these regions are to supply a consistent quantity of high-quality water to present and future generations, then they need effective laws and plans, efficient managing agencies, political interest and economic resources. Investments in research and developing water resource management plans are inefficient measures if they are not implemented with special emphasis on monitoring and inspection.

Estudo de casos de movimentos de massa às margens da BR101 no município de Campos dos Goytacazes/ RJ sentido Rio de Janeiro

Mass movements are continuous natural phenomena and external dynamics, like weathering and erosion processes. The study presents an analysis of mass movements along the BR101 highway in Campos dos Goytacazes, Rio de Janeiro. For this purpose, a field survey was carried out, in which the causes of 13 occurrences of mass movements were identified and analyzed. The occurrences were related to the deficiency and maintenance of drainage ways, associated with weathering activities, in a region of average susceptibility to erosion. The mass movements presented in the study offer low risk to the population.
