The observation of geological and geomorphological factors in coastal barriers to allows interpret the processes involved and the temporal trends over time. During the Holocene, the Balneario Torneiro barrier, located in the southern coast of Santa Catarina, prograded approximately 1.3 km, preserving the records of Urussanga river's system dynamics in surface and subsurface paleochannels. The presence of such features close to the boundary with the Pleistocene deposits up to the present coastline indicates that...
