Acesso em:.https://repositorio.ufpa.br/jspui/handle/2011/16370The Tucuruí Hydroelectric Power Plant has great socioeconomic and environmental importance for the southeast region of Pará, due to the formation of its artificial lake, resulting in changes in vegetation cover and loss of biodiversity. This study seeks to understand the dynamics of change in vegetation cover that occurred in the Água Fria Community, RDS Alcobaça, after the filling of the Tucuruí Reservoir, making it possible to understand the changes resulting from deforestation and subsidize proposals for interventions. Digital Image Processing (PDI) techniques were used, divided into stages: Landsat 8, Landsat 7 and Landsat 5 image acquisition; combination of spectral bands (Band 3 and Band 4) and atmospheric correction; NDVI calculation, map production and statistical analysis. To obtain the orbital images, the U.S.G.S. digital platform was used, in the months of July, August and September, from 1990 to 2020, with intervals of two years. The NDVI value showed no relationship with the years, indicating that during the years analyzed there was no significant reduction in the vegetation cover on the ground in the Água Fria community, in the Alcobaça RDS.Acesso Abertohttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Sensoriamento remotoSIGÁgua friaCobertura vegetalReservatório da UHE de TucuruíRemote sensingCold waterVegetal coverReservoir of the UHE TucuruíDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA SANITARIA::SANEAMENTO AMBIENTALCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOFISICA::SENSORIAMENTO REMOTOPLANEJAMENTO E GESTÃO AMBIENTALBARRAGEM E MEIO AMBIENTE
