Analise dos impactos causados por processos erosivos em Mata de São João-Ba: estudo de caso da Ba-093.

Abstract

In this paper we carry out an assessment of the susceptibility to erosive processes and their environmental impacts in the municipality of Mata de São João - BA, with a case study in gullies in the BA-093 road. Based on a bibliographic research, a characterization of the area was elaborated together with a synthesis about the conditions of erosive features, followed by field work that allowed for further detailing of the area with subjected to the erosion process. A search for satellite images was used to complement the understanding and evolution of the processes, making it possible to quantify the areas impacted by this phenomenon. From this study it was possible to associate the conditions of erosive processes with the physiographic aspects of the area, its temporal evolution and anthropic interference.
