Resumo

Landslide is a disasters typology that result in serious material and immaterial damage for society. In order to initiate the research on factors which may influence landslides in the Guandu river basin (ES), secondary data were taken from landslide scars and correlated to six physiographic factors: distance to roads, distance to rivers, slope , rainfall, pedology and land use. In the present study, the database was organized and manipulated using ArCGIS 10.3 software. Landslide Susceptibility Index (LSI) was applied to each of the factors. Contrary to what was expected, periods of high rainfall were not directly associated with this type of disaster occurrence in the basin in question. The results suggests that the degree of slope and typology of land use were the most correlated factors to the incidence of landslides in the basin.
