Ocean fronts are characterized by intense dynamics and vulnerability, due to the joint action of oceanographic, meteorological and anthropogenic forcing. As a result, there are several approaches to measuring this dynamic, highlighting those derived from remote sensing data, based on indicators such as the coastline, which is the interface between the marine and continental areas, and can be indicated by the limit between the dry and wet area, and which does not consider thickness or diameter. However, depending on the method and data applied, these predictions have greater or lesser uncertainty/spatial precision. The present investigation, based on data from the Landsat 5 and 8 satellite from 2011 to 2018, applied two approaches (DSAS and Cassie) to estimate variations in the coastline of Praia do Icaraí - Ceará. The results pointed to divergences between the approaches, where DSAS derived a scenario of predominance of erosive processes and Cassie a predominance of progradation. Based on campaigns and field data, as well as literature, it was found that the DSAS data are more congruent with the local reality, representing a net variation of -8.10 m and a variation rate of -2.32 m/year of the coastline.
