CAMARA, Michel et al. Geotechnologies as a subsidy for management of coastal environments: analysis of the decline in cliffs in the State of Rio Grande do Norte, Brazil, and its social and environmental implications. GOT [online]. 2019, n.16, pp.53-79. ISSN 2182-1267.  https://doi.org/10.17127/got/2019.16.003.

In the present work geoprocessing technics were used through digital image processing and multi temporal geographic analysis on a three decade time scale, using remote sensing images of 30 m and 6,5 m of spatial resolution to identify areas which suffered cliffs retreat of the coast of Rio Grande do Norte-Brazil, measure in m² the retreat and loss of initial characteristics of these environments, as well as to identify and analyze the socio-environmental impacts present. Five cliff areas retreat were found, with set back up to 78,061 m², putting at risk areas of heavy urban occupation, infrastructures facilities and access roads. Such information subsidize coastal management on these environment of the coast of Rio Grande do Norte.

Keywords : coastal management; coastal erosion; geomorphology.
