RESUMO

This dissertation describes a methodological approach to evaluate vulnerable areas to erosional processes using a combinstion of three maps: soil use, slope and geological map. Each attribute was reclassified to power of two generating 72 new categories, being reclassified again in to 4 categories: low vulnerability, vulnerable, high vulnerability and hight risk. . The comparison betwen the soil use and erosional vulnerability was carried out using GIS copabilities. The achieved results were considered satísfactory and the objetives of this thesis were reached because a suitable mapa representing areas with vulnerability to erosivel process was generated. An important characteristic of this dissertation is that the digital georeferenced database created can be use for different purposes. ...Note: The complete abstract is available with the full electronic digital thesis or dissertations
