O comportamento da linha de costa é um indicativo das tendências à que o sistema costeiro está submetido, pois é a interface de contato da transição continente-oceano. Neste sentido, a Restinga da Marambaia e os arcos praiais Macumba/Recreio-B

Barrier islands are low-lying elongated, narrow sandy deposits, usually parallel to the coastline, separated from the continent by a lagoon. Due to their low elevation above sea level, barrier islands are environments susceptible to drastic morpholog

Large-scale anthropic intervention in the coastal zone started mainly in the 19th century due to the need to accommodate increasingly larger ships in the port areas, and to the diffusion of the value of beaches as places for sea-bathing. Throughout t

Barrier islands are sedimentary bodies susceptible to changes in sediment supply, dominant physical processes, and sea level. The aim of this work was to study the sedimentary processes that established Marambaia Barrier Island (SE Brazil) as an elon

Sepetiba Bay located in Rio de Janeiro State (RJ), Southeast Brazil, is a region under heavy influence of seaports and mining. This feature puts at risk the quality of the local water system, especially due to the deposition of trace metals on the se

Due to their overall east-west orientation, the Rio de Janeiro oceanic urban beaches are exposed to high energy meteoceanographic events, exhibiting large spatial and temporal morphodynamic variability that affect their use and functionality. The mai
