The mountainous region of the state of Rio de Janeiro, goes through several environmental issues that move from landslides to floods, the recurrence of these events are marked by losses and deaths annually. This work has its central motivation in the application of a methodology for the analysis of the risk of flooding, using some plans of spatial information of easy access and/or elaboration. The methodology was carried out in three stages (data collection, parameters elaboration and validation), and found that the places in the Paquequer river sub-basin with the greatest risk of flooding are those occupied by the central core of the city. Thus, it was possible to measure the areas of risk to flooding in a preliminary way, with information plans that are relatively simple to generate. It is therefore considered that the methodology applied is an alternative for smaller municipalities, with reduced investment capacity, to promote more robust analysis of risk to flooding
