GEOLOGIA APLICADA À GESTÃO E PLANEJAMENTO URBANO – ANÁLISE DE MULTICRITÉRIO DA PORÇÃO SUL DA MANCHA URBANA DE NOVA LIMA E HONÓRIO BICALHO

Abstract

This paper shows the applied geology in urban areas, for geoenvironmental issues within human interaction with the physical environment. Those issues occur due to the lack of people knowledge and government planning about geological, morphological and hydrological features and their implication, putti ng those people into a vulnerability status. At this matter a Geoprocessing methodology of multicriteria analysis was used, allowing to synthesis results combined with many aspects. As an example were analyzed the urban expansion axis in the MG-30 highway between the south of Nova Lima city and Honório Bicalho district. Results indicate areas with susceptibility and vulnerability to risk of mass wasting due to the variables used in the modeling. The theme maps generated has the objective to support decision-making of the problems involved, for planning and mitigate risk inherent of the terrain, allowing an adequate interaction between urban expansion and physical environment.
