Geomorfologia antropogênica e as transformações do eixo leste de expansão urbana da cidade de Barreiras, Bahia

Abstract

The present research has as main objective to analyze how changes occurred in the East Side of Urban Expansions of the city of Barreiras - BA, from an Anthropogenic Geomorphology perspective. The methodological experts were based on the works of Lima (1990), Rodrigues (1997), Nir (1983) and Moroz-Caccia Gouveia (2010) that refer to the interpretation of human interferences on terrestrial physical systems wich in this case was interpreted within an urban area. Laboratory work was also carried out for the elaboration of cartographic products such as maps and topographic profiles, as well as several field works in the sense of verification as existing geomorphological and anthropogenic transformations. In general, the area was divided into five geomorphological levels, described between the Serra do Mimo and the right bank of the Grande river. The geomorphology of the area is between tabuliform relief of the mountain range, sloping areas with soft-wavy relief and flat areas on the right bank of the Grande river. The intense presence of real estate developments through urban acceleration is responsible for the transformation of the physical environment. The area is not fully transformed yet, but it has already shown signs of changes, such as which were categorized by different stages of perturbation and their related responses as forms, processes and materials correlative to these perturbations.
