Influência na variação dos volumes dos reservatórios na geração de energia: um estudo comparativo dos reservatórios do Nordeste – Sobradinho e Itaparica

Abstract

The construction of a reservoir provides economic and social benefits, but even with effective management, the change in volume is one of the factors that affects both the quality and quantity of water, causing reduction in the generation of hydroelectric power. This research aims to analyze the relevant factors that contribute to the volume change of two of the main reservoirs of the Brazilian Northeast: Sobradinho and Itaparica in an estimated period of 2006 to 2016. The environment, climate, temperature, humidity, evaporation, precipitation and flow are some of the aspects that affects the characterization of the variation in the volume of a reservoir. The methodology used in the research is based on historical operating, monitoring, control, geographic information, and capacity of the reservoirs, from documents originated queries from government institutions. The findings and conclusions of this study point to the contribution of a debate about the efficiency of reservoir production capacity taking into account the factors that depend on it for their maintenance.
