DINÂMICA SAZONAL E OS EFEITOS DAS RESSACAS NAS PRAIAS DE NITERÓI/RJ

Abstract

SEASONAL DYNAMICS AND THE RESULTS OF STORM WAVES UPON THE BEACHES OF NITERÓI/RJ Beaches are important for the protection of the coastal region against stormy waves. Therefore, beach conservation is fundamental but, contrary to that, beaches and related environments in the sandy barrier are frequently modified by human activity. The aim of this work is to present observations carried on from 1991 to 2002, on the beach dynamics of Niterói (RJ), as a response to seasonal stormy waves. Topographic profiles obtained on the beach and shoreface, pointed out that some parts of the beaches are more vulnerable to stormy waves activity and thus need special attention since problems with urban constructions already exist. These areas are the northwest extreme of Icaraí, both extremes of Piratininga and the northwest and center of Camboinhas beach.
