No litoral oriental do Rio Grande do Norte e inserido na Regi?o Metropolitana de Natal, localiza-se o Centro de Lan?amento da Barreira do Inferno, unidade institucionalmente protegida pela For?a A?rea Brasileira. A fim de proporcionar diretrizes de planejamento, este trabalho avaliou e mapeou os elementos geoambientais ligados aos processos erosivos h?dricos, permitindo a an?lise de suscetibilidade dos solos ? eros?o laminar na ?rea militar. Foram utilizadas t?cnicas de Geoprocessamento, em ambiente de Sistema de Informa??es Geogr?ficas (SIG) na an?lise qualitativa de mapas por t?cnica multicrit?rio aditiva. Foram realizadas visitas de campo, an?lises de imagens orbitais e avalia??o de dados climatol?gicos. Com a compara??o dos diversos produtos cartogr?ficos gerados atrav?s de ?lgebra de mapas, foi poss?vel avaliar o potencial erosivo da ?rea. Foi observado que em decorr?ncia da aus?ncia de a??es antr?picas predat?rias, recai sobre os atributos do meio f?sico as maiores relev?ncias para a an?lise da eros?o. Vistorias locais identificaram processos de ravinamento na ?rea das fal?sias e a t?cnica adotada mostrou-se adequada e eficiente para a representa??o espacial do potencial erosivo. / The production of information about the physical environment in a given region has a relevant role for the rational use of the soil, which can help to preserve the ecosystem, to develop more efficient works and to protect against soil loss. On the eastern coast of Rio Grande do Norte and located in the Metropolitan Region of Natal, is located the Launch Center of the Barreira do Inferno, an unit institutionally protected by the Brazilian Air Force. In order to provide planning guidelines, this work evaluated and mapped the geoenvironmental elements related to the water erosion process, allowing the analysis of soil susceptibility to laminar erosion in the military area. Geoprocessing techniques were used in a Geographic Information System (GIS) environment in the qualitative analysis of maps by additive multicriteria technique. Field visits, orbital image analysis and climatologic data evaluation were carried out. With the comparison of the different cartographic products generated through map algebra, it was possible to evaluate the erosive potential of the area. It was observed that due to the absence of predatory anthropic actions, the attributes of the physical environment have the greatest relevance for erosion analysis. Local surveys identified ravine processes in the area of the sea cliffs and the technique adopted proved to be adequate and efficient for the spatial representation of the erosive potential.
