Abstract	The main objective of this work is to characterize the soil and analyse the conditions for stability of slopes of the basin of Ligeiro river in the city of Pato Branco, southwest of Parana, using a mathematical model associated with the use of techniques for thematic mapping in GIS environment. The analysis for determining the rates of safety was accomplished through deterministic method, based on the concept of balance limit. This work involved the characterization in geotechnical field, testing in the laboratory and office functions. As a result of the interaction of all parameters, returned to values of Factor Security for each side. It was through this study, that the areas most likely to slip the slopes are associated with soil and the type Cambisolos and Neossolos found in areas with a slope above 20%. Areas stable appear more frequently in the areas of land Latossolos and Nitossolos, being located in areas of low slope, where the risk of occurrence of creep is virtually nil. The areas of occurrence of Cambisolos and Neosolos account for 84% of unstable areas of the basin where the soil is completely saturated. This is because part of being associated with the high slope. According to the results achieved in this study, it appears that the basin of Rio Light presents areas of instability, likely to slip, as a result of environmental factors, the physical environment and the occupation of manmade slopes, with removal of vegetation.
