Is currently witnessing inthe communication, News related to the impacts that the urban enviroment is suffering, especially those related to landslides, floods. These impacts are often linked the formo f ownership and occupancy of relief. Thus, those who suffer most from the situation are those who live in áreas of ssocial exclusion. The framework of exclusion and environmental degradation o four cities, in addition to submitting the majority of this population to a precarious and vulnerable insertion city, generatesw serious risk situtions during the most intense rainy periods affecting mainly the inhabitants os squatter settlements and slums, installed onsteep slopes, valley bottoms and áreas of tecnogenic deposits. Is thought to this issue the main objective of the research was, analyze, understand and identify the vulnerability of the relief to be occupied. For this, we analyzed cities of Presidente Prudente, whose urban site sits on a land of broad hills and Marília, that is set on a tabuliforme relief. To achieve the main objective, was necessary to perform a set of methodological procedures, among them: research and bilbiographical survey of the relevant issues; research and collection of social and environmental data; analysis of geomorphology and urban territorial expansion of these cities; definition and use of natural, social and economic indicators, allowed the realization of procedures for quantifying vulnerability, application of GIS techniques, for the preparation of material which supported the research (mapping and database); gathering and organizing data and fieldwork...
