Geomorphological constraining of tsunami (?) run-up in the Alcantarilha coastal lowland (Central Algarve, Portugal)

The Alcantarilha lowland, partly barred by a well developed barrier, including foredunes covering Pleistocene-Holocene beachrock and aeolianite, develops across the Alcantarilha infilled estuary, the beach-dune extending further SE until the Salgados lagoon. A topographic and coring survey revealed a peculiar feature at the leeward toe of the dune ridge close to the inlet area: a sandy fan with location, shape and morphology suggesting emplacement by single or multiple overwash of the barrier tip rather than tidal forcing. Its storm or tsunami origin and age are under investigation, and the only time-constrain available at present is that it should post-date ca. 6600 cal BP, the most recent in situ aeolianite (Moura et al., 2007) dated so far. METHODS, DATA SET AND RESULTS The fan boundaries are distinctive in aerial photos and satellite images: it is roughly ellipsoidal, ~200 m wide and ~300 m elongated paralleling the shoreline, rising ~ 0.9-1.2 m above the surrounding floodplain surface. Detailed topography shows that its short axis aligns with SW-NE elongated (though irregular) depressions in the dune crest, which link the beach with the fan. This could have favoured funnelling of, or erosion by, water overtopping the barrier but, in either case, the fan should correspond to extreme and abrupt event(s) of coastal flooding. 18 trenches and cores were performed in the exposed area of the fan and nearby flood plain to obtain samples and data on its sedimentology, lithostratigraphy and geometry. The fan consists of well sorted and rounded sand (Fig. 2). It thins away and wedges out landwards of the apex (located near Alc29T) where it is partly covered by dune sand. Its lower boundary is undulating and marked by textural contrast between sand (fan) and underlying mud (alluvial/lagoonal); an accumulation of marine-sourced perforated pebbles showing limited lateral continuity may pinpoint this boundary near the foredune (core Alc 25, ca. 80 m westward of profile in Fig.1); mud-balls were also observed immediately above this surface in cores and trenches. As the washover was probably emplaced in a barred lagoonal/estuarine floodplain setting, the fan’s northern outer belt is enclosed by low-energy sediments (not shown in Fig. 2).

The ways behind the railways: Algarve's railway line. Technique transfers and transport development in Southern Portugal

Esta dissertação pretende contribuir para um melhor conhecimento da complexidade das redes de transferência de conhecimentos e técnicas, no domínio da engenharia civil e mais concretamente através dos caminhos-de-ferro, nos séculos XIX e XX. Em Portugal, os caminhos-de-ferro estiveram no cerne de um vasto debate, sobretudo político, concomitante com uma instabilidade crescente no cenário político e uma fase de fragilidade económica. É neste contexto que a Linha do Sul e Sueste vai ser construída (seguida pela sua extensão até Vila Real de Santo António e pela construção do ramal de Portimão, que chegará a Lagos). Este empreendimento é uma clara ilustração da realidade portuguesa de então, no que concerne ao desenvolvimento desta rede de transportes, que nos permite, igualmente, conhecer e compreender quem interveio no processo de construção da linha (os engenheiros, as empresas, entre outros aspectos) e assim determinar quais as influências e transferências técnicas que tiveram lugar; RESUMEE: Cette mémoire attire à la contribution pour une meilleure connaissance de la complexité des réseaux de transfert de techniques et connaissances qui ont eu lieu dans le domaine de l’ingénierie civile, surtout dans les chemins de fer, au XIXème et XXème siècles. Au Portugal, les chemins de fer sont été le cerne d’un très vaste débat, coïncidant avec une croissante instabilité dans le scenario politique et aussi une phase économique fragile. C’est dans ce contexte que la Ligne du Sud et Sud-est va être bâti (suivi par l’extension jusqu’à Vila Real de Santo António et la construction de l’embranchement ferroviaire Portimão). Cette entreprise c’est une illustration claire de la réalité portugaise, en concernant l’implémentation de cette réseau de transport, que nous permettre de comprendre et également bien connaitre qui a intervenu dans le processus de construction de la ligne (les ingénieurs, entreprises, etcetera), ainsi que déterminer les influences et les transferts techniques qui ont eu lieu; ABSTRACT: With this master’s thesis, the aim is to be able to contribute to a better understanding of the complex network of technique’s and knowledge transfers, that took place within the field of civil engineering, in the 19th and 20th centuries, namely on the railways. In Portugal, railways take-up was a wide and ample debate, coinciding with an uprising turmoil on the Portuguese political outskirt and a phase of economic frailty. It’s in this context that the construction of the South and Southeast Line took place (followed, later on, by its extension until Vila Real de Santo António and by the construction of the Portimão’s branch). This enterprise is, as we pretend to prove in this master’s thesis, a clear example of the Portuguese reality, enabling us to understand and to get to know those who intervened in the construction’s process (the engineers and the companies) as well as determining influences and technique transfers that have taken place.

Central Algarve karst system tufa-related dynamics, Portugal.

Geomorphological mapping is a powerful instrument improving the geomorphological interpretation and understanding of the processes and forms used in landscape studies, with the ability of organizing different thematic layers in the same map. The presented map provide relevant information about the different geomorphological units of the central Algarve (i.e. the Carboniferous flysch mountains; the Barrocal, with marly and karstified subunits), where a karst system is prominent. Solution karst morphologies and large dry areas are common in the elevated areas of the Barrocal, suggesting deep circulation of groundwater. These recharge areas feed the perched aquifers of the area, where discharge is controlled by the impervious lithologies (clay-rich strata of the turbidites, marls and argilites) in the valley bottoms or other leaks in dammed aquifers. In springs related to the main aquifers tufa are actively being formed and, close coupled to spring location, different tufa depositional systems develop.

Provenance of upper Triassic sandstone, southwest Iberia (Alentejo and Algarve basins): tracing variability in the sources

Laser ablation ICP-MS U–Pb analyses have been conducted on detrital zircon of Upper Triassic sandstone from the Alentejo and Algarve basins in southwest Iberia. The predominance of Neoproterozoic, Devonian, Paleoproterozoic and Carboniferous detrital zircon ages confirms previous studies that indicate the locus of the sediment source of the late Triassic Alentejo Basin in the pre-Mesozoic basement of the South Portuguese and Ossa-Morena zones. Suitable sources for the Upper Triassic Algarve sandstone are the Upper Devonian–Lower Carboniferous of the South Portuguese Zone (Phyllite–Quartzite and Tercenas formations) and the Meguma Terrane (present-day in Nova Scotia). Spatial variations of the sediment sources of both Upper Triassic basins suggest a more complex history of drainage than previously documented involving other source rocks located outside present-day Iberia. The two Triassic basins were isolated from each other with the detrital transport being controlled by two independent drainage systems. This study is important for the reconstruction of the late Triassic paleogeography in a place where, later, the opening of the Central Atlantic Ocean took place separating Europe from North America.

Adaptação às alterações climáticas do plano de contingência do sistema multimunicipal de abastecimento de água do Algarve

Face ao aumento que se tem vindo a observar da população, especialmente a população flutuante, e a alteração nos hábitos de consumo de água, com destaque para os últimos 20 anos, a região do Algarve poderá enfrentar em anos secos um cenário onde a disponibilidade de recursos hídricos naturais seja reduzida face à procura. Em 2005 foi desenvolvido um plano de contingência para o Sistema Multimunicipal de Abastecimento de Água do Algarve (SMAAA). O plano prevê a possibilidade de reactivação de antigas captações subterrâneas municipais para reforço do abastecimento público em situações de contingência nesta região. A presente dissertação apresenta a avaliação dos principais impactos das projecções dos modelos de clima para o fim do século no SMAAA, nomeadamente ao nível da disponibilidade de água na origem e da procura de água para consumo humano, e a adaptação do plano de contingência face a esses impactos. /RESUME: Faced with a population increase, special one related with tourism, and also with changes in water consumption habits that has been occurring mostly in the last 20 years, the Algarve region in hydrologic dry years may face serious water shortage in a scenario where water resources are scarce. Being so, in 2005 a contingency plan was developed for the Algarve's Multimunicipal Bulk System (AMBS). The plan includes the possibility of reactivating old water capitations, to reinforce the water public distribution upon contingency situation in the region. The present dissertation evaluates the main impacts of the climatic change forecasted by model projections throughout the end of the century on the AMBS, Iooking more specifically at the water availability and the water demand for public consumption, and the adaptation of the contingency plan to those impacts.

Mover para melhor nascer: liberdade de movimentos e posições verticais no primeiro estádio do trabalho de parto

A Organização Mundial de Saúde destaca a deambulação e a adoção de posições verticais pela parturiente, como práticas demonstradamente benéficas, devendo ser estimuladas pela enfermeira obstetra na condução do trabalho de parto e parto normal, em situações de baixo risco obstétrico. O projeto preconizou a promoção da deambulação e o incentivo à adoção de posições verticais na fase ativa do trabalho de parto. As intervenções de enfermagem na promoção destas práticas foram avaliadas na equipa de enfermeiros obstetras do Serviço de Urgência Obstétrica e Ginecológica do Centro Hospitalar Barreiro-Montijo, Entidade Pública Empresarial e num grupo de parturientes, através da aplicação de questionários. As necessidades dos enfermeiros obstetras e das parturientes determinaram a realização de ações formativas e educacionais e a elaboração de materiais informativos de suporte à prática assistencial. A avaliação do projeto demonstrou que ainda existem práticas a serem melhoradas, sendo a sua continuidade vantajosa para profissionais e parturientes; ABSTRACT: TITLE: Move to Better Birth - Freedom of Movement and Upright Positions in First Stage of Labor. The World Health Organization highlights ambulation and adoption of vertical position by the woman, as demonstrated beneficial practices and should be encouraged by obstetric nurses in the conduct of obstetric labor and normal delivery, in low risk situations. The project advocated for the promotion of ambulation and encouragement for the adoption of vertical positions in the active phase of labor. Nursing interventions to promote these practices were evaluated in the obstetric nurses team of Obstetric and Gynecological Emergency Department from Hospital Center Barreiro-Montijo, Business Public Entity, and in a group of women in labor, through the use of questionnaires. The needs of obstetric nurses and women in labor determined the realization of training and educacional activities and the development of information materials to support the care practice. The project evaluation demonstrates that there are still practices to be improved, and its continuity being advantageous for professionals and women in labor.
