Abstract:

The coastline between Rio de Janeiro and Cabo Frio is characterized by successive long beach arcs, oriented in the East-West direction. The beaches are separated by rocky headlands resulting from the erosional retreat of the front scour of the coastal range. Occupation of the coastal zone has sharply increased since 1974, as a consequence of better accessibility afforded by the construction of a bridge between Rio de Janeiro and Niteroi, as well as the growth of the metropolitan area. This work presents a preliminary view of some of the problems occurring along the coast between Niteroi and Cabo Frio. These problems become more serious within the next 50 to 150 years, causing highly valued property to be lost as a consequence of an already expected rise of the relative sea level. The paper discusses study methodology, characteristics of the littoral, and other aspects of the subject.
