Hazard and Exposure Assessment to Sea Level Rise in Mainland Portugal
Silva, Andreia Alves da; Trindade, J.; Rocha, JorgeCoastal sustainable land use hinges on sea level rise (SLR) as a critical driver of climate risk mitigation, shaping adaptative coastal zone management, and fostering transitions towards resilient communities. The mainland Portuguese coastline, exposed to the energetic North Atlantic wave regime, faces frequent erosion and coastal flooding. By 2100, the consequences of these hazards are expected to intensify as...
Sustainable land use: policy implications of systematic land regularization in ...
Carrilho, João; Dgedge, Gustavo; Santos, Pedro Pinto; Trindade, J.Security of land tenure is key to achieve the sustainable development goal of eradicating poverty and can be improved through the regularization of rights to land, property, and natural resources. Making cities and human settlements sustainable, requires participatory and integrated land use planning, accounting for the land’s potential and constraints, with a view to medium and long-term use. The government of...
Methodology for sea level rise hazard assessment in the exposed coastal zone of...
Trindade, J.; Reis, Eusébio; Rocha, Jorge; dos Santos, Pedro; RAC Garcia, R Garcia; Oliveira, Sérgio; Silva, Andreia; Pinheiro, SamuelFuture scenarios of sea level rise in Portugal are expected to put at risk sensitive areas from a natural and urban point of view. This research proposes a methodology for the assessment of sea level rise Hazard zones using the evaluation of permanent and episodic com-ponents as important factors to predict flooding and coastal erosion hazards for the Shared Socioeconomic Pathway 1, 2 and 5 scenarios, in 2040, ...
Susceptibility and exposure to sea level rise in the Sado estuary and in the Ar...
Zêzere, J.L.; Oliveira, S.C; Pereira, S.; Melo, R.; Santos, P.P.; Reis, E.; Garcia, R.A.C.; Trindade, J.; Morais, R.; Rocha, J.Sea level rising is a major driver of three climate hazards in the Sado estuary and in the Arrábida coastal zone: estuarine flooding, coastal flooding and cliff retreat. In this work, the susceptibility to estuarine flooding, coastal flooding and cliff retreat is assessed for the present and at the end of the century, for the SSP2-4.5 and SSP5-8.5 emission scenarios. The exposure of people and assets to the con...
Late Holocene natural and man induced environmental changes in Western Iberian ...
Ramos Pereira, A.; Ramos, C.; Danielsen, R.; Trindade, J.; Soares, A.M.; Granja, H.; Martins, J.M.M.; Torres, A.; Araújo-Gomes, J.The Western coast of the Iberian Peninsula stands as an interface between both the Atlantic and Mediterranean climatic influences and marine / fluvial conditions. The paper aims to assess the environmental changes in the last ca 6000 years (both natural and anthropogenic induced) using multiproxy analysis (geomorphological and sedimentological data, elemental and stable isotope content, microfossil assemblages,...
Análise secular da frequência de cheias na bacia hidrográfica do Rio Vez
Gonçalves, Glória; Trindade, J.O estudo das cheias é necessário na prevenção das consequências para a população, dependendo da frequência, magnitude, localização dos elementos expostos e nível de vulnerabilidade dos mesmos. O estudo secular de fontes da imprensa periódica (1900-2015), validada com dados de caudal e de precipitação, permitiu estabelecer a frequência das cheias na bacia hidrográfica do rio Vez. 84,3 % das notícias sobre as che...
Combining Artificial Neural Networks and GIS fundamentals for Coastal erosion p...
Peponi, Angeliki; Morgado, Paulo; Trindade, J.The complexities of coupled environmental and human systems across the space and time of fragile systems challenge new data-driven methodologies. Combining geographic information systems (GIS) and artificial neural networks (ANN) allows us to design a model that forecasts the erosion changes in Costa da Caparica, Lisbon, Portugal, for 2021, with a high accuracy level. The GIS–ANN model proves to be a powerful t...

Vestígios do Tsunami de 1755: um indicador negligenciado no litoral de Portugal...
Ramos Pereira, A.; Trindade, J.; Araujo Gomes, J.; Leandro, A.Os tsunamis podem originar fenómenos de inundações marinhas extremas em áreas costeiras com efeitos devastadores. Este capítulo refere parte da investigação que tem vindo a ser desenvolvida sobre os vestígios do tsunami de 1755 em Portugal continental, talvez o mais devastador registado até hoje no nosso território. O contexto geoestrutural do país torna-o susceptível a este fenómeno extremo que deixou marcas n...
Dinâmica de um indicador de linha de costa no arco Caparica-Espichel: caso de e...
Sousa, N.; Trindade, J.; Ramos Pereira, A.Este estudo pretende avaliar a dinâmica da linha de costa no arco Caparica-Espichel, nos últimos 40 anos. Esta avaliação baseia-se na análise de fotografias aéreas e ortofotomapas das décadas de 1960, 1980, 1990 e de 2000. Incluem-se: (i) a avaliação de incertezas associadas à definição, georreferenciação e interpretação de imagens aéreas; (ii) a escolha dos indicadores de linha de costa; e (iii) a determinação...
