Mapeamento das áreas de risco de deslizamento em encostas na cidade de Fraiburgo – SC

Abstract

This work had as thematic the mapping and description of the risks areas from the city of Fraiburgo. First of all, slope maps were generated to identify possibles hazard areas (were pointed as hazard areas, the regions with a slope greater than 30%). These maps were shown to the Civil Defense representant who identified que places that really had problems. Then, location maps were created for all the risks points and all the risks areas were ranked in: Low, Medium, High and Very High Risk. In most of the mapped areas, the risk was more associated with the hazard than local vulnerability and, most of these sites had their risks related to construction infrastructure problems and not with isolated natural hazards.
