ANÁLISE COMPARATIVA DO TRANSPORTE DE SEDIMENTOS NAS PRAIAS DE PONTA NEGRA E DA BARREIRA DO INFERNO. 2017. 50 f. TCC (Graduação) - Curso de Engenharia Ambiental, Departamento de Engenharia Civil, Universidade Federal do Rio Grande do Norte, Natal, 2017.https://repositorio.ufrn.br/handle/123456789/37036The coast of Rio Grande do Norte comprises a range of about 400 km of beautiful beaches, the main motor that drives the Potiguar economy through tourism. The beaches of the RN’s coast, in addition to attracting people from all over the world, are essentially representative structures of coastal dynamics phenomena, fundamentally influenced by sediment transport along the coastline. In recent years, erosion processes have been occurring in a much accentuated way in Ponta Negra Beach, a postcard of the state capital, due to the decrease in the beach strip, a factor closely associated with the reduced contribution of coastal sediments, observed by ARAÚJO (2015). Congruently, GURGEL (2017) carried out a study of the coastal dynamics of the neighboring beach, Barreira do Inferno Beach, and observed a discrete longitudinal transport of sediments. Based on these studies, this work sought to understand the factors that influence the transportation of coastal sediments and through a bibliographical study of the areas of the beaches of Ponta Negra and the Barreira do Inferno, realize a comparative analysis, regarding sediment transport among them, in order to ascertain if there is a possible relation of one over the other, considering the factors that collaborate in the coastal dynamics and how these may possibly affect their morphologies. From the analysis performed, several similarities were observed between the study beaches, such as the predominance in the direction of the winds and the currents being from east and east-southeast, sediment transport in the South-North direction and a great divergence in the volumes of sediments transported, being 700,000 m3/year in Ponta Negra and 50,000 m3/year in the Barreira do Inferno. Due to their locations, coastal dynamics and the comparison of the aspects that influence the longitudinal transport of sediments, it was concluded that there is possibly a strong relation between the study beaches, strengthening the hypothesis that the Barreira do Inferno Beach is a major influencer of the Ponta Negra Beach in terms of sediment dynamics.openAccessAttribution 3.0https://creativecommons.org/licenses/by/3.0/Ponta NegraZona costeiraTransporte longitudinal de sedimentosBarreira do InfernobachelorThesisCNPQ::ENGENHARIAS
