MAPPING OF SUSCEPTIBILITY TO NATURAL DISASTERS THROUGH THE USE OF FUZZY LOGIC IN THE MUNICIPALITY OF ALEGRE-ES

Abstract

Among the various problems that Brazil currently faces, few have a social and human impact as significant as those related to natural phenomena and their negative consequences for society, especially geotechnical events and floods. In a country like Brazil, which suffers from a lack of urban planning and adequate investments in infrastructure to prevent this type of occurrence in various spheres, recurring tragedies accumulate year after year, always accompanied by the perception that they could have been avoided. On the other hand, the geosciences have been increasingly open to new geotechnologies. In this context, the present work presented new paths that offer useful resources to seek short to medium-term solutions, helping to overcome the various challenges related to this theme, both at the national, regional and municipal levels. Thus, the methodology related to geotechnologies and its various techniques was used, with emphasis on Fuzzy Logic, which was the main pillar of this study. In the end, the methodology adopted proved to be effective in pointing out the areas of greatest susceptibility to geotechnical problems and flooding, revealing great potential for future applications of greater complexity and scope.
