Previous issue date: 2014-04-04 / The objective of this Doctoral Thesis was monitoring, in trimestral scale, the coastal
morphology of the Northeastern coast sections of Rio Grande do Norte State, in Brazil, which
is an area of Potiguar Basin influenced by the oil industry activities. The studied sections
compose coastal areas with intense sedimentary erosion and high environmental sensitivity to
the oil spill. In order to achieve the general objective of this study, the work has been
systematized in four steps. The first one refers to the evaluation of the geomorphological data
acquisition methodologies used on Digital Elevation Model (DEM) of sandy beaches. The
data has been obtained from Soledade beach, located on the Northeastern coast of Rio Grande
Norte. The second step has been centered on the increasing of the reference geodetic
infrastructure to accomplish the geodetic survey of the studied area by implanting a station in
Corta Cachorro Barrier Island and by conducting monitoring geodetic surveys to understand
the beach system based on the Coastline (CL) and on DEM multitemporal analysis. The third
phase has been related to the usage of the methodology developed by Santos; Amaro (2011)
and Santos et al. (2012) for the surveying, processing, representation, integration and analysis
of Coastlines from sandy coast, which have been obtained through geodetic techniques of
positioning, morphological change analysis and sediment transport. The fourth stage
represents the innovation of surveys in coastal environment by using the Terrestrial Laser
Scanning (TLS), based on Light Detection and Ranging (LiDAR), to evaluate a highly eroded
section on Soledade beach where the oil industry structures are located. The evaluation has
been achieved through high-precision DEM and accuracy during the modeling of the coast
morphology changes. The result analysis of the integrated study about the spatial and
temporal interrelations of the intense coastal processes in areas of building cycles and
destruction of beaches has allowed identifying the causes and consequences of the intense
coastal erosion in exposed beach sections and in barrier islands / O objetivo da Tese de Doutorado foi o monitoramento da morfologia costeira em escala
trimestral de trechos do Litoral Setentrional do Estado do Rio Grande do Norte, ?rea da Bacia
Potiguar sob a influ?ncia das atividades petrol?feras. Trata-se de setores costeiros marcados
por intensa eros?o sedimentar e de alta sensibilidade ambiental ao derramamento de ?leo.
Para atingir o objetivo geral deste estudo, o trabalho foi sistematizado em quatro etapas. A
primeira etapa apresenta a avalia??o das metodologias de aquisi??o de dados geomorfol?gicos
utilizada na modelagem digital de eleva??o de praias arenosas a partir de dados obtidos na
praia de Soledade, localizada no Litoral Setentrional do Rio Grande do Norte. A segunda
etapa foi a amplia??o da infraestrutura geod?sica de refer?ncia para a realiza??o dos
levantamentos geod?sicos da ?rea de estudo atrav?s da implanta??o de uma esta??o na ilha
barreira de Corta Cachorro e de levantamentos geod?sicos de monitoramento para o
entendimento do sistema praial com uso de an?lises multitemporal de LC e MDE. A terceira
etapa consistiu na utiliza??o da metodologia geod?sica para o levantamento, processamento,
representa??o, integra??o e an?lises de Linhas de Costa (LC) de litorais arenosos obtidos por
t?cnicas geod?sicas de posicionamento, an?lise das altera??es morfol?gicas e transporte de
sedimentos A quarta etapa foi definida pela inova??o de levantamentos em ambientes
costeiros com a utiliza??o do Laser Esc?ner Terrestre (LiDAR) para avalia??o de um trecho
submetido a intensa eros?o na praia de Soledade onde est?o instaladas infraestruturas da
ind?stria petrol?fera, por meio de MDE de alta precis?o e acur?cia no modelamento das
modifica??es na morfologia costeira. As an?lises dos resultados do estudo integrado das
interrela??es espaciais e temporais dos intensos processos costeiros atuantes na ?rea ao longo
de ciclos de constru??o e destrui??o das praias permitiram identificar as causas e
consequ?ncias da intensa eros?o costeira em setores de praias expostas e ilhas barreiras
