The coastal zone, an area of extreme dynamism due to the interaction between marine and continental systems, also subject to climatic phenomena, has been undergoing consequent changes due to increasingly recurrent and severe climate changes and this has directly implied the shoreline,either in the form of erosion or progradation. Thus, using methodologies associated with geoprocessing techniques it was possible to verify that in the last 13 years the beach stretch comprising the Resex of Prainha do Canto Verde, located on the east coast of Ceará, presented erosion rates ranging from -4,14 m/yr and -2.33 m/yr (EPR) and from -3.66 m/yr to -1.77 m/yr (LRR), in total terms this represents a shoreline retreat that ranged from slightly more than 50 m, maximum and minimum 23 m according to the statistics used by the DSAS extension.
