SUMMARY:

The growth of large urban centers requires significant investment in infrastructure. In Brazil, unfortunately, most of the capitals don’t receive enough financing in basic areas such as sanitation, drainage and paving. The absence or inefficiency in the provision of these essential public services, combined with the irregular construction of low-income family housing in places with geological-geotechnical risks, favor the occurrence of landslides, especially during rainy periods. In recent years, the government has sought to propose public policies in partnership with Civil Defense, aiming to minimize events of geotechnical mass movements and their respective damage (material and loss of life), highlighting: revision of municipal master plans, expropriation of homes built in risky regions, construction of civil containment elements such as retaining walls, creation of landslide warning systems, among others. Warning systems for natural disasters, such as landslides and floods, have undergone significant advances in recent decades, especially those managed on platforms that use Geographic Information System (GIS) to deal with the spatial and temporal treatment of information, facilitating the analysis of a range of variables on a single platform quickly and effectively. Since the 1980s, dozens of technical-scientific works on mapping potential regions for mass movements have been developed. This research proposes the development of an unprecedented methodology for analyzing the risks of landslides in urban centers, using a GIS platform and considering the spatial and temporal variation of precipitation. To apply the proposed tool, a village in the southern region of Belo Horizonte – MG will be used, with an estimated area of 50,000 m². To carry out the map algebra, the conditioning factors that favor slope landslides that will be used are: geology, geomorphology, pedology, vegetation, climate, hydrology, land use and occupation. To operationalize the proposal, the multicriteria method of decision support AHP will be used, making possible to assess the weight (relevance) of each criterion adopted using the opinion of experts. It is expected, through this research, to propose a GIS tool capable of developing dynamic maps that indicate the potential for lanslides risk and that present themselves as an important element to support the Civil Defense (end user of the tool) in directing its activities, as well as helping the government in choosing regions that demand infrastructure investments, contributing to the scientific community and society.
