                         Brumado river basin unsing the Normalized Difference Vegetation 
                         Index (NDVI) calculated within Landsat 5 images in a temporal 
                         scale (07/10/1987 and 06/10/2011). NDVI is one of the most popular 
                         vegetation index, because it can compensate differences in 
                         illumination conditions, surface slope and any other unknown 
                         reason. Its proved that the vegetation has influence in the 
                         quality and the quantity of water in a basin. The studied area is 
                         located in the Center-South region of Bahia, and is an important 
                         tributary of Contas River, belonging to the Eastern Atlantic 
                         hydrographic region. The river basin is the basis for the 
                         management of water resources; for that, studies in these areas 
                         are so important. The images were processed in a GIS software. The 
                         results show the efficiency of the NDVI and image processing 
                         techniques to portray the land cover of an area and the changes 
                         that had happened. The percentage of the area without vegetation 
                         or covered by low density biomass increased among the years, while 
                         the portion covered by medium and high density biomass has 
                         decreased. Certainly, this had happened due the human impact 
                         against the vegetated areas, mostly for agricultural uses.",
