Identificação de áreas de riscos geomorfológicos em área urbana consolidada: estudo de caso no município de Anchieta - SC

Abstract

The migratory process for the great urban centers intensified in Brazil from the second half of the twentieth century. Many cities recorded an accelerated population increase, triggering situations related to lack of planning and consequently areas of risk. In this way, it is understood that research related to the risk areas of geomorphological aspects, can assist in urban planning and decision-making by competent bodies. The main objective was the development of an environmental diagnosis, focusing on the geomorphological risks, in the consolidated urban area of the municipality of Anchieta - Santa Catarina, Brazil. The analysis of the results consisted in the organization of identified geomorphological risks, for each characterized risk a risk degree was defined according to the Manual of Planning in Civil Defense (1999). The identification of the identified geomorphological risk areas resulted in the final considerations of this research, revealing situations of great social relevance, in total, 19 risk areas were identified, 7 of them with very high risk characteristics.
