River, inclunding Tibau City, Grossos City and part of Mossor? City. Geologicaly, this area is composed by rokcs of Potiguar basin, represented by Cretaceous, Tertiary and Quaternary sediments. This area is characterizer by the intense action of cosatal processes (eolic and costal tranports, generalized erosion, alteration in the sediments balance and coast modification), reponsable for it?s morfological instability, also the antropic interference, where the iol industry is located, next Mossor? City, and also the salt exploration industry and the tendency of expantion of shrimp cultivation. This report had as objective the multitemporalgeoenvorimentalmonitoring of the region by recognizingin the field and analizingimages of orbital sensors of diferents years of last four decades. This analisys was achieved by Digital Images Procesing (DIP) thecnics, com subsidized, in a GIS, the preparion of Thematic Maps of natural resources (Geology, Geomorphology and Use & Ocupatios of Earth) and the Envorimental Sensivity to Oil Spilling, main objective os this project. Such technics constitute important tools of envoriment monitoring and maneging, indicating tendencies of antropic of natural growing, making possible the apropiated planning of development of the region, where the steps can be indicated minimized possibles envorimental impacts caused by antropics interferencies on the region, mainly those related to industrial activities, and oil industry above all. Researchs of this nature are very important to the analisys and ordered manegements of use and ocupation of coastal places / A ?rea estudada encontra-selocalizada na por??o costeira do litoral setentrional do estado do Rio Grande do Norte, mais precisamente numa zona ? oeste do Rio Apodi-Mossor?, englobando os Munic?pios de Tibau, Grossos e parte de Munic?pio de Mossor?. Geologicamente esta ?rea ? constitu?da por litotipos da Bacia Potiguar, representados por sedimentos cret?ceos, terci?rios e quatern?rios. ? caracterizada pela intensa a??o de processos costeiros (transporte litor?neo e e?lico, eros?o generalizada, altera??es no balan?o de sedimentos e modifica??es na linha de costa) respons?veis por sua instabilidade morfol?gica, al?m da interfer?ncia antr?pica, destacando-se a presen?a da ind?stria petrol?fera nas proximidades da Cidade de Mossor?. Pode-se ainda citar a explora??o salineira e a forte tend?ncia de expans?o da carcinicultura. Este trabalho objetivou o monitoramento geoambiental mutitemporal da regi?o por meio do reconhecimento de fei??es de campo e da an?lise de imagens de sensores orbitais de diferentes datas das ultimas quatro d?cadas. Esta an?lise se deu atrav?s de t?cnicas de Processamento Digital de Imagens, as quais subsidiaram, em um SIG, a elabora??o de Mapas Tem?ticos dos recursos naturais (Geologia, Geomorfologia e Uso e Ocupa??o do Solo) e de Sensibilidade Ambiental ao Derramamento do ?leo, principal objetivo deste trabalho. Tais t?cnicas constituem importantes ferramentas ao monitoramento e gerenciamento ambiental, denotando tend?ncias de crescimento antr?pico e natural, possibilitando o planejamento adequado para o desenvolvimento da regi?o, onde medidas poder?o ser apontadas para minimizar poss?veis impactos ambientais causados por interfer?ncias antr?picas na regi?o, principalmente ?quelas relacionadas ?s atividades industriais, sobretudo relacionadas ? industria do petr?leo. Estudos dessa natureza s?o de vital import?ncia na an?lise e gerenciamento ordenado do uso e ocupa??o dos terrenos costeiros
