Resumo
The phisiographic aspects, the intrinsic characteristics of the lands and the population growth that have been intensified during the last decade, resulted in a disorganized occupation on the slope, have brought the occurrence of mass movements in Vitória – E.S., mainly during the rainy periods. This dissertation focus the identification of mass movement problems in the city, through the study and analysis of a local inventory, characterization of the movements and the determination of the indicators of behavior. The inventory was realized through the register of 1122 geological and geologic–geotecnic accidents in the city of Vitória, during a period of 18 years, from 1984 to 2001, using Geografic Information System (GIS’s) as a basic tool of data register. The characterization of the mass movement involves the gathering of data from the inventory, in the form of graphics, and an analysis of the determination of the mass movement conditional factors in the city. The analysis procedure used in the determination of the indicators of behavior models used comparative methods based on conditional factors of risk, in order to obtain points of homogeneous behavior of the mass movement of Vitória. The advance of knowledge of the problems involved in the mass movements in Vitória looks toward the definition of the correct counter measures in mitigating the consequences, through the suggestions of the implementation of a preventive plan.
