Acesso em: .https://repositorio.ufpa.br/handle/2011/11642The beaches are dynamic and very sensitive, therefore they are formed by sand and gravel that, influenced by meteorologic, hydrologic, oceanographic and anthropic processes, being these responsible ones for the morpho-sedimentary transformations. The studies on the morpho-sedimentary variability of the beaches allows the identification of the places and the periods of greater/minor erosion and deposition in the beaches, that also serve as coastal protection for adjacent ecosystems, urban activities and as habitat for several species of the biodiversity. The estuarine sandy beaches of the Amor and the Artistas are located in the Caratateua island, situated about 30km of Belém, capital of the of Pará state. The Caratateua island is included in the estuarine region of the Marajoara Gulf, under the influence of the Amazonian Equatorial climate (annual rainfall of 2,700 3,000 mm), and with dry (June to November) and wet (December to May) periods, and transitional period (June and November). The tidal amplitude rise to 3,65m - 4,7 m during the neap tides. The study area is developed on the sediments of the Grupo Barreiras and Pós-Barreiras. The monitoring of the morphology and the sedimentology of the transversal profiles of the Amor and the Artistas beaches have been carried during four field stages during 12 months, due to the regional sazonality (2003/2004 – dry, 2004 – rainy. June and, October February of 2004 - transistion). In the Beach of the Amor, three profiles in each stage were executed and one profile in the the Artistas Beach for stage, totalizing 148 sand samples (37 for stage - 10 for profile in the Beach of Amor and 7 for profile in the Beach of the Artistas). The results showns that the beach of the Amor presented an classification of terrace of low tide with small dunes and extensive zone of intermaré (210m), beyond the occurrence of gutters and low declivity (ß=0,95º). Nevertheless, in the beach of the Artistas, is characterized by an reflective beach environment with ~8m high cliffs, an narrow intertidal zone (60m) and high declivity (ß=5,5º). The Amor beach is classified as an Terrace of Low Tide during the dry period (October/2003-2004) and Transversal Chains of Return and Bars during the rainy period (February/2004) and transition (Juny/2004). The Artistas beach is classified as intermediate beach, with two morphologic periods of training: Terrace of low tide, during the dry period (October/2003-2004), while that in the rainy period (February/2004), the intermediate morphologic period of training was of Bank and Longitudinal Gutter, with an presence of zone of intermaré above and banks and gutters, that are located in the zone of intermaré below/inframaré.Acesso AbertoPraiasSedimentosIlha de Caratateua - PADissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIASGEOLOGIA
