Análise das condições ambientais do trecho de vazão reduzida da usina hidrelétrica de Cachoeira Dourada - MG

Abstract

Hydroelectric plants are fundamental to the country's development, this is due to the fact that they are one of the main sources of electricity generation in Brazil. However, in the construction of a plant it is necessary to make changes to the landscape, which can be harmful to the environment. Thus, the present work was developed with the objective of analyzing the environmental conditions in the Reduced Flow Section of the Enel Green Power Cachoeira Dourada SA hydroelectric plant in the physical aspect of the section downstream of the reservoir, where an investigative analysis was carried out in the field to score and verify the presence of features that showed changes in the landscape. The work was divided into two parts, the first being an office study, and the second part was a field study. Despite the socio-environmental impacts caused in the construction process of the hydroelectric plant, such as the diversion of the river's natural channel, flooded areas, landscape modification, among others, he observed that the area under study had few environmental impacts in relation to what was expected, as he expected - there was deforestation, waste and erosion, which may be a reflection of the presence of warning signs inserted on the side of the highway that gives access to the Low Flow Section, prohibiting the practice of recreational activities on site.
