Estudo de suscetibilidade a movimentos gravitacionais de massa e inundações na região urbana de Patos de Minas, Minas Gerais

Abstract

Every year Brazil registers thousands of accidents considered natural disasters, where the State of Minas Gerais contributes yearly, mainly accidents linked to the intense rains. Thus, this study aims to indicate areas that have the propensity to develop natural physical processes linked to mass movement and flooding in the urban perimeter of the city of Patos de Minas. From maps of land use and occupation, soil classes, hypsometry, average annual precipitation, slope, road mesh and NDVI, map algebra and analytical hierarchy process was applied. As the result, the susceptibility classification of the area was obtained. It was concluded that the urban perimeter has medium to high susceptibility for mass movements and flooding, preventive measures should be taken to avoid major accidents.
