Morphological System

A planície costeira brasileira, em especial a do Nordeste do Brasil, apresenta um sistema morfológico que sofre diversas pressões do ponto de vista do uso e ocupação dos seus espaços. Logo, o entendimento da dinâmica natural e espacial desse ambiente requer a adoção de metodologias que contemplem uma abordagem em múltiplas escalas. Neste sentido, este trabalho tem o intuito de analisar as múltiplas morfologias associadas a praia das Fontes, em Beberibe-CE, em diferentes escalas taxonômicas. Esta análise auxiliou na realização de um prognostico das condições ambientais e de sua capacidade de suporte. Metodologicamente aplicou-se a proposta de Bertrand (1971), adotando-se apenas as unidades inferiores que inclui os níveis taxonômicos regionais e/ou locais, compreendendo os geossistemas, geofáciese os geótopos. Os resultados alcançados foram satisfatórios, uma vez que as unidades mapeadas foram validadas em atividades de campo para reconhecimento do produto cartográfico.Palavras-chave: Análise Multiescalar.

Therefore, the understanding of the natural and spatial dynamics of this environment requires the adoption of methodologies that contemplate a multi-scale approach. In this sense, this work has the purpose of analyzing the multiple morphologies associated to Praia das Fontes, in Beberibe-CE, at different taxonomic scales. This analysis assisted in the accomplishment of a prognosis of the environmental conditions and their support capacity. Methodologically Bertrand's (1972) proposal was applied, adopting only the lower units that includes regional and / or local taxonomic levels, including geosystems, geophysics and geo-objects. The results were satisfactory, since the mapped units were validated in field activities to recognize the cartographic product.Keywords: Multiscalar Analysis. Coastal Geomorphology.

AbstractWell-developed elevated beaches. deltaic deposits, marine-boulder pavements and wave-washed bedrock surfaces are found from Cape Bernacchi north to Granite Harbour. The highest measured marine feature, an elevated beach at Dunlop Island, is 20 m (67 ft) above sea-level. The highest beaches at Marble Point and Cape Roberts, about 48 km (30 miles) apart, are about 20 m (66 ft) above sea-level. The marine limit between these two points is, therefore, essentially horizontal. The highest beach at Cape Bernacchi. approximately 4.8 km (3 miles) south of Marble Point, is about 12 m (40 ft) above sea-level, Well-developed elevated beaches disappear about 3.2 km (2 miles) south of Cape Bernacchi and are not found between this point and Koettlitz Glacier.These beaches post-date the youngest glaciation recognized in the lower Wright Valley. A 14C analysis of an elephant seal buried in a 13 m (44 ft) beach at Marble Point indicates that this beach is 4450 ± 150 years old. As sea-level at this time was approximately 3 m (10 ft) lower than at present. the Marble Point area has risen isostatically about 16 m (54 ft) during the last 4450 ± 150 years.Pitted beaches, beaches deposited on ice, a buried elephant seal and gravel ridges deposited by ice indicate that all of the beaches were formed in a climate like that now found in the area.
