USO DE GEOTECNOLOGIAS (SIG) PARA MAPEAMENTO DE ÁREAS INUNDÁVEIS EM ZONAS URBANAS: ESTUDO DE CASO BAIRRO DE BUNHIÇA

Abstract

Floods can damage the economy with high financial and social losses. This is the problem in the Bunhiça neighborhood, specifically in Mulumate, Cell "C", Municipality of Matola. The development of modern space technologies makes it possible to visualize the Earth through collected data and surface images (Santos, 2012 cited by Freitas, 2018). Ο General objective is to map areas susceptible to flooding. Specifically, the objectives consist of: Identifying areas prone to flooding; Analyze the factors that contribute to the occurrence of floods; Assess the socio-environmental impacts arising from floods. The methodological procedures involved: data collection, organization and processing, analysis, synthesis and integration of cartographic information. Satellite images (SASPlanet), topographic maps and bibliography were used. The cartography was generated by GIS geoprocessing. The results indicate susceptibility to the occurrence of floods, and Territorial Planning measures must be taken in order to minimize their impacts. The use of this information can contribute to decision-making related to disaster prevention plans, guidance of Planning Policies and Territorial Ordering in the management of flood risks.
