Uso de geotecnologias para mapeamento da suscetibilidade a inundações e escorregamentos em Teófilo Otoni, Minas Gerais: potencialidades e limitações

Abstract

With the rapid and disorderly growth of cities, especially in underdeveloped countries, increasing populations begin to occupy areas susceptible to flooding and landslides. As a result, significant efforts by various social actors are aimed at identifying and mapping these areas, using different technological tools available for such purposes. Therefore, the objective of this work is to discuss the potential of methods that employ geotechnologies for the identification, classification and mapping of areas susceptible to flooding and landslides in Teófilo Otoni, Minas Gerais. Through the use of satellite images, multicriteria analysis and field work, it was possible to map the susceptibility to the highlighted phenomena, resulting in preliminary maps, whose applicability can serve the future territorial planning of the municipality. The potentialities and limitations of the adopted methods are presented and discussed, by associating them with databases of past flood occurrences and the recognition and mapping of landslide scars on slopes.
