The municipality of Goytacazes is established in areas previously bathed by extensive water bodies. Several areas of this municipality are as a result of major human interventions for drainage of low lands in the region aiming mainly to expand agricultural areas. However, due to bad management of drainage network, the region still suffers from floods, mainly because of the nature of geomorphological land, home flooded. The zoning of areas subject to flooding in this sense, it is presented as an extremely valuable tool for organizing and planning the use and occupation of a region, especially those where these flood events are recurring, as is the case of Goytacazes. This instrument is able to identify critical areas and direct the use of land according to its characteristics. The objective of this work was to offer from a Digital Terrain Model, a tool to perform the Zoning Areas Susceptible to Flooding of a representative area of Baixada Camper, using as a tool to support an Information System (GIS) in the case this study, we used the ArcGIS software, version 9.3. Results show the lower areas of the region studied, comparing the information found in data preservation areas and occupation of the area, which indicates the current study as a support tool for planning and environmental policies in order to rationalize the use of land in the Baixada Camper.
