Water footprint of the Sobradinho hydropower plant, Northeastern Brazil

Hydroelectricity is responsible for the greatest fraction of the electric energy generated in Brazil. The water footprint of hydropower plants (WFP) is an important indicator of the sustainable and efficient use of water resources. In this context, WFP of the Sobradinho Hydropower Plant was determin...

The water footprint of hydropower plants (WFP) is an important indicator of the sustainable and efficient use of water resources. In this context, WFP of the Sobradinho Hydropower Plant was determined for the period from 2003 to 2012, taking into account the reservoir’s historical variation for the flooded area. To accomplish this, monthly series of electric energy production, flooded area, evaporation and evapotranspiration rates were used. Average gross and net evaporation were 2,031 and 1,577 mm year-1, respectively. The average power generation of this facility in the analyzed period was 462 MW, and the flooded area of its reservoir presented an average value of 3,054 km². Based on the monthly data, the gross and net water footprints were, respectively, 417 and 325 m³ GJ-1. Based on these results, it can be concluded that the changes in the reservoir’s area exert direct and important influence on the WFP estimates of the Sobradinho hydropower plant. The WFP estimates in this study were different from other studies that adopted a constant value of 4,214 km² for this reservoir’s area, which is taken based on the normal water level of the plant operation.A hidroeletricidade é responsável por grande parte da produção brasileira de energia elétrica. Assim, a pegada hídrica de usinas hidrelétricas apresenta-se como um importante indicador para análise e discussão de questões relacionadas ao uso sustentável e eficiente dos recursos hídricos. Nesse contexto, foi caracterizada a pegada hídrica da Usina Hidrelétrica de Sobradinho, no período de 2003 a 2012, considerando a variação histórica da área alagada pelo reservatório. Para isto, foram utilizadas séries mensais de geração, área inundada, evaporação e evapotranspiração. A evaporação bruta e líquida, médias do período de análise, foi de 2.031 e 1.577 mm ano-1, respectivamente. A energia média gerada no período foi de 462 MW médio, enquanto a área de inundação do reservatório apresentou um valor médio de 3.054 km2. Com base nos dados mensais estimou-se a pegada hídrica bruta e líquida em 417 e 325 m³ GJ-1, respectivamente. A partir dos resultados pode-se concluir que a variação da área do reservatório exerce influência direta e significativa na estimativa da pegada hídrica da Usina Hidrelétrica de Sobradinho. Os valores obtidos de pegada hídrica diferem de outras estimativas que adotaram o valor constante de 4.214 km2, correspondente a área do reservatório no nível d’água normal de operação da usina.Revista Ambiente & Água2019-09-23T12:43:39Z2019-09-23T12:43:39Z2018info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf1980-993Xhttp://dx.doi.org/10.4136/ambi-agua.2134https://locus.ufv.br//handle/123456789/27095engv. 13, n. 03, e. 2134, 2018info:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVPereira, Silvio BuenoVieira, Nayara Paula AndradeBueno, Eduardo de OliveiraMello, Carlos Rogério de2024-07-12T06:28:42Zoai:locus.ufv.br:123456789/27095Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T06:28:42LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
