MAPEAMENTO DA FRAGILIDADE AMBIENTAL À PROCESSOS EROSIVOS LINEARES E MOVIMENTOS DE MASSA NA ÁREA DE PROTEÇÃO AMBIENTAL DA BACIA HIDROGRÁFICA DO RIO MACHADO- MG
Abstract
The present paper aimed at mapping the environmental fragility of Rio Machado watershed in order to find linear soil erosion processes as well as mass movement, seeking to analyze which zones are more likely to suffer from such processes. The area where this study was conducted correspond to lands that integrate the Environmental Protection Area of Rio Machado watershed, located in Southern Minas Gerais. The methodology adopted consists in an adaptation of the methodological process developed by Garófalo e Ferreira (2015), through techniques of geospatial analysis in Geographic Information Systems to map the environmental fragility. The results showed the most fragile areas are located in southern and northern parts of the watershed, mainly in Espírito Santo do Dourado and São João da Mata and the least fragile areas are mainly in Poço Fundo e Machado. It could be evidenced that the most fragile areas present several processes of soil erosion.
