Resumen:
Two aerial surveys were processed with Structure from Motion -Multiview-Stereo with a Co-Alignment approach in two sectors ofa wetland: El Picaflor (EP) and El Sarandı (ES). Shoreline changeswere analysed with Digital Shoreline Analysis System (DSAS) usinghigh-resolution orthophotos and change detection was calculatedwith M3C2. In EP the shoreline changes rate averages 0.71 m/yrand the M3C2 comparison shows that the coast is mainly erosional.In ES the shoreline rates of change averages 0.59 m/yr andthe M3C2 comparison shows both erosion and deposition. WhenEP and ES were compared, the main differences are land use,orientation of the coast, and the presence of intertidal vegetation.The use of the Co-Alignment approach together with DSASproves to be a valuable technique for monitoring shorelinechanges at a high spatial and temporal resolution in this wetlandand can be applied to study other coastal wetlands worldwide.
