A Serra do Mar pertence ao complexo litorâneo brasileiro, preenchendo todo o litoral desde Santa Catarina até o Rio de Janeiro. As feições de seu relevo são peculiares, resultantes de um tectonismo recente com acelerado processo de intemperismo, que acarreta em feições distintas ao longo de todo o complexo da Serra do Mar. A evolução deste relevo tem como fator resultante a adequação da drenagem às falhas e rupturas presentes nas rochas. Desta forma a evolução da Serra do Mar e compreensão das anomalias de drenagem, tal como a Captura Fluvial do alto rio Guaratuba, passa a ser ponto de investigação desta pesquisa, utilizando datação por Luminescência Opticamente Estimulada (LOE). Para o desenvolvimento da pesquisa foi proposta uma divisão do relevo em três compartimentos geomorfológicos (Planalto, Planície do alto rio Guaratuba, Bordas e escarpa da Serra). A compartimentação foi elaborada respeitando as morfologias e a drenagem local, baseada na teoria de AbSaber (1969) sobre a forma de se estudar o Quaternário. Foram elaboradas cartas temáticas (declividade, hipsometria, orientação das vertentes, etc.) para um embasamento visual da teoria discutida no trabalho, vinculando a elas os pontos de coleta das amostras. A partir da compartimentação do relevo desenvolveu-se atividade de campo para coleta de material sedimentar de possíveis trechos do antigo leito fluvial. As amostras coletadas foram trabalhadas em laboratório por datação através da técnica de LOE, utilizando-se o protocolo de alíquota única (SAR). As amostras foram trabalhadas quimicamente para que se obtivesse o grão de quartzo na sua forma mais pura. A partir dos dados adquiridos através da IX datação, as informações foram trabalhadas em planilhas e softwares voltados para a interpretação dos dados. Os valores alcançados foram discutidos ao longo da pesquisa, justificando-se os apontamentos positivos e negativos das amostras. Os dados obtidos concordam com a literatura abordada sobre a evolução geomorfológica da Serra do Mar. / The Serra do Mar mountain range belongs to the Brazilian coastal complex which runs from the state of Santa Catarina to Rio de Janeiro. Its relief has peculiar features, derived from a recent tectonism with accelerated weathering process, which leads to distinct features throughout the complex of the Serra do Mar. The evolution of this relief results in the drainage adequacy to the failures and disruptions found in the rocks. Therefore, the evolution of the Serra do Mar and understanding of drainage anomalies, such as the Guaratuba upper river fluvial capture, becomes the point of investigation in this research, using Optically Stimulated Luminescence (OSL) for dating. For the development of the research, the relief was divided into three geomorphologic compartments (Plateau, Guaratuba upper river plain, Borders and Scarp of the Serra do Mar). The compartmentation was developed in compliance with the morphologies and local drainage, based on the Ab\'Saber Theory (1969) on how to study the Quaternary. Thematic maps were drawn (slope, hypsometry, orientation of the strands, etc.) for a visual basis of the theory discussed in the thesis, linking them to the points of sample collection. From the relief compartmentation a field activity was carried out for the collection of sedimentary material of possible sections of the old riverbed. The samples were processed in the laboratory through the technique of dating OSL, using the single-aliquot regenerative-dose (SAR). Samples were chemically worked out to obtain the quartz grain in its pure form. From the data acquired through dating, the information was analyzed on spreadsheets and software focused on the interpretation of data. The values achieved were discussed throughout the thesis research to explain any positive XI and negative results of the samples. The data obtained agree with the literature on the geomorphological evolution of the Serra do Mar that is presented in the thesis.

Le principal objectif de cette étude est de mieux comprendre et de quantifier les paramètres et les processus de contrôle de la morphologie et de l’évolution stratigraphique du nord du bassin de Santos pour les derniers 49,5 my. Il s’agit de déconvoluer le signal climatique et tectonique dans l’enregistrement sédimentaire à travers de l’analyse sismique à diverses résolutions (~7-8 s et ~400 ms de penetration), de l’analyse lithologique et le calage chrono stratigraphique des limites de séquence majeures, à partir de 19 forages industriels. La modélisation stratigraphique par Dionisos combinée à nos observations nous a permis de quantifier les paramètres majeurs qui vont contrôler l’architecture sédimentaire à différentes échelles de temps. 9 séquences stratigraphiques sont ainsi identifiées et regroupées en 3 mégaséquences (Mégaséquences A, B et C): (i) La Mégaséquence A est caractérisée par des systèmes deltaïques qui viennent remplir l’espace d’accommodation créé par le fluage du sel vers le bassin entre la baie de Guanabara et Cabo Frio. Le flux sédimentaire qui la nourrit est mis en relation avec le paléo fleuve du Paraíba do Sul qui se deplace vers le bassin de Campos à la fin du development de la Mégaséquence et resulte dans une drastique reduction des flux du bassin de Santos; (ii) La Mégasequence B est caractérisée par la rétrogradation de tous les systèmes sédimentaires comme une réponse directe à la diminution des flux sédimentaires. Cette megasequence est aussi caracterisée par l’implantation des depots contouritiques entre 30 et 21 Ma, problablement liés à des changements dans la circulation oceanique dû a l’ouverture de la passage de Drake et de la Tasmanie (entre 37 et 28 Ma); (iii) La Mégasequence C est caractérisée par une progradation et le déplacement des offlap breaks de 70 km vers l’océan, depuis les derniers 11.5 my comme réponse de l’augmentation de flux sédimentaire qui caractérise le passage à des cycles glacio-eustatiques marqués dans le Quaternaire. / The main objective of this study is to better understand and to quantify experimentally the main parameters that control the geomorphological and stratigraphic evolution of the Cenozoic sedimentary succession of the northeast Santos basin, Brazil, in the last 49.5 my. For this purpose, a variety of combining methologies were used, such as: seismic analysis of a dataset composed of different resolution levels (~7-8 s and ~400 ms penetration), chronostratigraphic and lithological data from 19 exploratory wells and stratigraphic modeling. Seismic analysis and stratigraphic modelling led to the identification of 9 main stratigraphic sequences that could be grouped into 3 megasequences (Megasequences A, B and C): (i) Megasequence A is characterized by deltaic features developed into a ramp feature located between Guanabara Bay and Cabo Frio. The formation of this delta resulted in a sedimentary overcharge that induced the basinward salt migration. The sedimentary input that feeds this delta was interpreted as related to an ancient Paraíba do Sul River that diversion to the Campos basin at the end of the megasequence development, resulting in a dramatically reduce the sedimentary influxes into Santos basin; (ii) Megasequence B is characterized by the retrogradational trend of sedimentary systems that offset offlap break of surfaces developed at 30 and 21 Ma about 78 km landward. This megasequence is also characterized by the beginning of conturites deposition related to the changes of oceanic circulation due to the opening of Drake and Tasmanian passages; (iii) Megasequence C is characterized by progradational systems that resulted in the coastline shift about 70 km oceanwards, in the last 11.5 my. The dominant progradational trend of this sequence is interpreted as a response of the increase in the sedimentary influx rate intensified by the spectral characteristics and amplitude of the glacial-induced eustatic signal that characterizes the Quaternary period.

[pt] O litoral norte fluminense do RJ compreende um grande domínio geomorfológico costeiro do estado, formado por depósitos quaternários a partir de sucessivas variações do nível do mar somados a contribuição de processos fluviais e marinhos, permitindo o desenvolvimento de um complexo deltaico em uma extensa região. A partir dos anos 2000, uma série de trabalhos têm se dedicado a compreender aspectos evolutivos detalhados destas regiões, em especial as planícies costeiras localizadas ao sul e ao norte da atual foz. Pesquisas recentes detalharam o mecanismo morfodinâmico responsável pela formação e evolução das barreiras costeiras presentes na planície norte do delta, assim como reuniram uma série de evidências associadas aos antigos ambientes que indicam que o processo atualmente em curso no litoral, teria sido responsável pela formação de boa parte da planície costeira holocênica, localizada ao norte da desembocadura fluvial. Neste contexto, a presente pesquisa tem como objetivo caracterizar o atual ambiente de sedimentação em termos de morfologia e sedimentação, possibilitando relacionar o mecanismo atualmente em curso com os registros pretéritos estudados. Para isso, foram realizadas sondagens, monitoramento morfodinâmico, coleta de sedimentos, batimetria na zona marinha e na laguna presente na região, além de fotointerpretações. Em laboratório, também foram realizadas análises granulométricas e quantificações de carbonatos e matéria orgânica, possibilitando ainda correlacionar os dados de superfície com os de subsuperfície, a fim de se obter melhor precisão nas interpretações. A pesquisa evidenciou que o processo formador da planície Holocênica é o mesmo observado no litoral atual, acrescentou um entendimento melhor e mais detalhado sobre a morfodinâmica local, além de sugerir que a energia hidrossedimentar do rio Paraíba do Sul veio diminuindo nos últimos anos. / [en] The fluminense north coast region of Rio de Janeiro comprises a large coastal geomorphological domain in the state, formed by Quaternary deposits where they developed from successive variations in sea level as well the contribution of River and marine processes allowing the development of a complex delta in an extensive region. The current sedimentation stage of this complex is represented by the holocenic delta of Paraíba do Sul, built after the last marine transgressive maximum. From the 2000s onwards, a series of works have been dedicated to understanding the detailed evolutionary aspects of these regions, especially the coastal plains located on the south and north of the current mouth. These plains have important geomorphological contrasts, due to the occurrence of distinct evolutionary processes responsible for coastal progradation. To the north of the mouth, the presence of a coastline marked by the presence of beach ridges interspersed with muddy depressions stands out, the result of the successive incorporation of barrier-lagoon systems, formed from the emergence of initially submerged sandy barriers. Recently researches investigated of the morphodynamic mechanism responsible for the formation and evolution of the coastal barriers present in the northern delta plain, as well as gathered a series of evidence associated with ancient environments that indicate the process currently underway on the coast would have been responsible for much of the Holocene plain located north of the River mouth. In the context this research aims to characterize the current sedimentation environment in terms of morphology and sedimentation, making it possible to relate the mechanism currently in progress with the previous records studied. For this, surveys, morphodynamic monitoring, sediment collection, bathymetry were carried out as well as photointerpretations. In the laboratory, granulometric analyzes, quantification of carbonates and organic matter were carried out, allowing for the correlation of surface data with subsurface in order to obtain better precision in the interpretations. This research showed that formation process of the Holocene plain is the same in progress today, added a better and more detailed understanding of the local morphodynamics, suggesting that the hydrosedimentary energy of the Paraíba do Sul River has been decreasing in recent years.

Le Rhin dans son parcours franco-allemand a été aménagé depuis deux siècles pour la protection contre les inondations, la navigation et la production hydro-électrique. La rectification (19ème siècle), la régularisation (1930) et la construction du Grand Canal d’Alsace (1928-1959) ont profondément altéré le fonctionnement hydro-sédimentaire du « Vieux Rhin », tronçon de 50 km court-circuité entre les barrages de Kembs et de Breisach, conduisant à une réduction de la complexité du tracé en plan, une incision, un pavage du fond du lit et une simplification des habitats aquatiques et riverains. La possibilité de restaurer le transport sédimentaire et la dynamique alluviale du Vieux Rhin est évaluée au sein de projets portés par la Région Alsace et EDF. Dans ce cadre, la présente thèse repose sur deux types d’approches de la géomorphologie fluviale, historique et expérimentale, afin de répondre à la problématique de restauration morpho-écologique du tronçon fluvial. Ce travail, basé sur la collecte de données anciennes et de terrain, ainsi que sur la quantification des évolutions morphologiques à différents niveaux scalaires, a conduit à une meilleure compréhension de la trajectoire temporelle d’ajustement de l’hydrosystème et à une estimation de sa sensibilité aux changements. Le suivi géomorphologique d’un test de recharge sédimentaire conduit sur un site-pilote a servi également à évaluer la pertinence de ce type d’intervention, à travers l’analyse des bénéfices et des risques environnementaux potentiels. L'ensemble des résultats obtenus a permis d’apporter aux gestionnaires des éléments d'aide à la réflexion pour orienter les stratégies de restauration ainsi que des indicateurs physiques d’évaluation des futures actions / The Upper Rhine River has undergone several anthropogenic modifications since the last two centuries for flood protection, navigation and hydropower generation. Channel rectification, groyne fields and lateral “Grand Canal of Alsace” construction heavily altered the hydro-sedimentary functioning of the 50 km-long "Old Rhine" by-passed between Kembs and Breisach: channel pattern simplification, bed incision, armouring and ecological habitats alterations. Two complementary projects have been initiated to restore the sediment transport and the reach alluvial dynamics. This thesis investigated space-time and experimental geomorphic approaches within the morpho-ecological restoration of a modified fluvial system. The archive and field data-based work aimed at understanding the Old Rhine historical trajectory. The geomorphological monitoring of a gravel input experiment also consisted in evaluating environmental benefits and potential risks for society and proposing physical assessment indicators. Results will help river stakeholders to define strategies to restore morphological processes and associated ecological functions in the Old Rhine.

Esta tesis aplicando las bases teórico-metodológicas de la geoecología de montaña trata de establecer la organización altitudinal del paisaje de montaña del Macizo Central de los Picos de Europa. El macizo es considerado como un sistema organizado altitudinalmente en pisos geoecológicos, como resultado de los cambios morfo/bioclimáticos derivados de la altitud. El relieve se presenta como el elemento clave en la configuración del paisaje natural de esta montaña, hasta el punto de llegar a definirlo como un paisaje fundamentalmente geomorfológico.Se diferencian dos pisos de alta montaña y dos pisos de montaña media, separados entre sí por una franja de transición geoecológica: a) Alta Montaña Rocosa (> 2.200 m), b) Alta Montaña Supraforestal (1.800-2.200 m), c) Franja de Transición Geoecológica entre AM/MM (1.400-1.600 m,), d) Montaña Media Forestal (600/800 y 1.400/1.600 m), e) Laderas Bajas-Fondos de Valle de Montaña Media, M.M. muy antropizada (< 600/800 m). / This Thesis applies the theoretical basis of mountain geoecology to establish the altitudinal organization of the mountain landscape of the Central Massif of Picos de Europa (Cantabrian Range). The massif is considered to be a system altitudinally organized in belts, as result of the morpho/bioclimatic changes deriving from altitude. Relief is the main element of the natural landscape of this mountain massif, to the extent of defining it as a fundamentally geomorphological landscape. Two geoecological belts of high mountain and two of the middle mountain are distinguished, connected by a geoecological transition belt: a) Rocky high mountain (> 2200 m), b) Upper forest high mountain belt (1800 and 2200 m): c) Geoecological Transition HM/MM (1400/1600 and 1800 m), d) Forest Middle Mountain (600/800 and 1400/1600 m), and e) Low slopes and valley bottoms - Middle mountain highly antropized (<600/800 m).

From the bigger knowledge about the Vereda subsystem is possible to characterize it as a Cerrado typical landscape, which has as its symbol, the Buriti palm (Mauritia vinifera Mart.) generally it is built since a drainage system surface regulated by regional climate regime. The Vereda subsystem has a great relationship with higher soil moisture, which can be obtained from the leakage of the water table, poor drainage of an area or proximity to waterways. Its importance is due to be generally in headwater areas, but can occur in other environments, besides being a refuge for fauna and flora. The balance of Vereda subsystem is essential for the maintenance of water resources in Cerrado. Given the importance of the Vereda subsystem, is the purpose of this study, in which we seek to know it better. Thus, our aim was to understand the factors of origin and development of Vereda subsystem, as well as the analysis of its geomorphological modeling in different area of the traditional tabular surface, performing this analysis in the municipality of Goiandira, which is located in Goiás Southeast, in order to be a spatial area that presents particular landscape, helping the development of research, besides being a good representation of Cerrado area and also the Biome socio-economic occupation process, with livestock as the main activity responsible for the land use. By analyzing the current geomorphological modeling and field research found that this is perfectly capable to represent the Vereda subsystem which is presented all over the Cerrado. However, it was required some changes in nomenclature and also a better characterization of each of the eight existing geomorphological models. In Goiandira city was found 100 Vereda subsystems that occur in less dissected areas and usually in places that provide a water table interception or moisture soil. It was found in the Goiandira municipality, six of eight geomorphological models of existing Vereda. It was also found that the main sources in the area surveyed are in Vereda environment and that they are going through an intense environmental degradation process and its preservation is necessary to maintain the water resources of the municipality and the region. / No presente estudo destaca-se o subsistema de Vereda, que integra as várias fitofisionomias típicas do Cerrado lhe conferindo grande especificidade paisagística. A partir do maior conhecimento sobre o subsistema de Vereda é possível caracterizá-lo como uma paisagem típica do Cerrado, que possui como símbolo, a palmeira buriti (Mauritia vinifera Mart.), geralmente constituí-se a partir de um sistema de drenagem superficial regulado pelo regime climático regional. O subsistema de Vereda possui grande relação com a alta umidade do solo, que pode ser proveniente do extravasamento do lençol aquífero, da má drenagem de uma área ou da proximidade a cursos de água. Sua importância ocorre em virtude de se constituir, geralmente, em áreas de nascentes, embora possa ocorrer em outros ambientes, além de ser um refúgio para a fauna e flora. O equilíbrio do subsistema de Vereda é fundamental para a manutenção dos recursos hídricos da região do Cerrado. Diante da importância do subsistema de Vereda, ocorre à proposição deste estudo, no qual busca-se conhecê-lo melhor. Desse modo, objetivou-se, compreender os fatores de origem e de desenvolvimento do subsistema de Vereda, bem como, a análise da sua modelagem geomorfológica em área diferente das tradicionais Superfícies Tabulares, realizando esta análise no município de Goiandira, que está localizado no Sudeste do estado de Goiás, tendo em vista ser um recorte espacial que apresenta particularidades paisagísticas, ajudando no desenvolvimento da pesquisa, além de ser uma área de boa representatividade do bioma Cerrado e também do processo de ocupação sócio-econômica do Bioma, tendo a pecuária como a principal atividade responsável pelo uso de suas terras. Com a análise da atual modelagem geomorfológica e a pesquisa de campo constatou-se que esta é perfeitamente capaz de representar o subsistema de Vereda presente em todo o bioma Cerrado. Entretanto, foram necessárias algumas alterações na nomenclatura e também uma melhor caracterização de cada um dos oito modelos geomorfológicos existentes. No município de Goiandira foram encontrados 100 subsistemas de Vereda que ocorrem em áreas menos dissecadas e, geralmente, locais em que o relevo proporciona a interceptação de um lençol aquífero ou alta umidade do solo. Foram encontrados no município de Goiandira, seis dos oito modelos geomorfológicos de Vereda existentes. Constatou-se também que as principais nascentes na área pesquisada encontram-se em ambiente de Vereda e que as mesmas, estão passando por um intenso processo de degradação ambiental, sendo necessária as suas preservações para a manutenção dos recursos hídricos do município e da região.
