This work has as main objective to further knowledge about some environmental relations in the field of urban slopes and submit proposals for modeling susceptibility to landslides so common in the city of Rio de Janeiro. Following a thought, this dissertation will have as secondary objectives, the production of various intermediate products, layers of environmental data will be used to assist the preparation of the final product and comparative analysis of other models and local laws. Urban areas are environments where human occupation and concentration become intense and, most often, cluttered, become sensitive to gradual local anthropogenic changes, as they are intensified in frequency and intensity. Urban slopes today are great example for environmental degradation, endangering the safety and quality of life of its population, constituting a stage of ecological conflicts. The fast and unplanned growth that has occurred in many cities in developing countries is largely responsible for environmental changes, mischaracterize often original environment. As these changes are made, a number of geomorphic responses, typical of large cities such as landslides and floods, which occur frequently, and often, being not high rainfall totals required for these processes occur (Guerra, 2006). Mankind has been undergoing a process of urbanization, the Brazilian urban population in 2010 comprised approximately 84 percent of total population.
