Abstract Reliable predictions of future inundation extent within estuaries require a precise evaluation extreme sea levels and the application accurate numerical models that account for physical processes driving estuarine hydrodynamics. In this study, methodology integrates estimation local with high-resolution modeling was applied to assess in five systems located on Portuguese Coast. The main findings obtained were compared available results from popular bathtub approach, disregards...

A colonização japonesa (1910-1945) foi caracterizada por uma intensa subjugação do povo coreano, deixando marcas que influenciam a forma como esses dois países se relacionam nos dias atuais, questão das “mulheres de conforto”. Durante Segunda Guerra Mundial, o governo militar japonês esteve sob controle inúmeras “estações conforto” distribuídas pela Ásia, nas quais mulheres diferentes foram coagidas servirem sexualmente os soldados japoneses. Essa questão, intensamente julgada...

Flooding assessment under sea level rise scenarios: Ria de Aveiro case studySea is an important consequence of climate change with a significant impact on society and ecosystems. The present work aims to assess the sensitivity marginal flooded area rise. A previous version hydrodynamic model ELCIRC was improved extending its numerical grid through inclusion intertidal areas topography. configuration calibrated comparing predictions surface elevation...

Ports constitute a significant influence in the economic activity coastal areas through operations and infrastructures to facilitate land maritime transport of cargo. are located multi-dimensional environment facing ocean river hazards. Higher warming scenarios indicate Europe’s ports will be exposed higher risk due increase extreme sea levels (ESL), combination mean level, tide, storm surge. Located on west Iberia Peninsula, Aveiro Port is lagoon flows, contributing flood risk. This study...

Shallow coastal lagoons driven by tidal processes are extremely dynamic environments prone to continuous natural and anthropogenic pressures. The hydrodynamics of these systems deeply depends on the effect local morphology propagation, so their permanent evolution constantly changes dependent processes. For this reason, present work aims review main characteristics Ria de Aveiro hydrodynamics, a shallow lagoon located at Atlantic Coast Portugal, evaluating its over last 30 years (between...

Mean sea-level is expected to rise significantly by 2100 in all scenarios, including those compatible with the objectives of Paris Climate Agreement. Global sea level projections indicate devastating implications for populations, ecosystem services and biodiversity. The (SLR) on low-lying islands coastal regions communities are substantial require deep-rooted coping measures. In absence adequate responses coping, Mozambique record huge losses, an impact economy development many sectors its...

Influence of morphological changes in a lagoon flooding extension: case study Ria de Aveiro (Portugal) In: Conley, D.C., Masselink, G., Russell, P.E. O'Hare, T.J. (eds.)Coastal lagoons are interface zones where land, water atmosphere interact dynamic balance that is constantly being changed by natural human influence. The hydrodynamics morphology these coastal systems continuously adapt to the forcing agents show complex...

Coastal floods are currently a strong threat to socioeconomic activities established on the margins of lagoons and estuaries, as well their ecological equilibrium, situation that is expected become even more worrying in future climate change context. The Ria de Aveiro lagoon, located northwest coast Portugal, not an exception these threats, especially considering low topography its which has led several flood events past. growing concerns with regions stem from mean sea level (MSL) rise...

Abstract The precise evaluation of the conservation status salt marshes, understanding mechanisms behind loss and degradation anticipation future threats are fundamental to assist management solutions able reverse declining trend observed in these environments. Previous methods combining remote sensing hydrodynamic modelling have been revealed be effective assessing restricted but unable characterise dynamics marshes at estuarine scale. This study proposes an alternative methodology identify...

Picado, A., Lopes, C.L., Mendes, R., Vaz, N. and Dias, J.M., 2013. Storm surge impact in the hydrodynamics of a tidal lagoon: case Ria de Aveiro.Storm surges are hazardous phenomenon, since they may flood large coastal areas, causing socio-economical habitation losses. Thus, study their characteristics effects regions is crucial to prevent negative consequences. This work aims at assessing storm lagoon located north-western Portuguese coast (Ria Aveiro). amplitudes 0.58 m, 0.84 m 1.17 for 2,...

Pereira, C., Coelho, Ribeiro, A., Fortunato, Lopes, C.L. and Dias, J.M., 2013. Numerical modelling of shoreline evolution in the Aveiro coast, Portugal – climate change scenariosIn Northwest coast Portugal, is leading to several problems, such as loss territory infrastructural damages, mainly caused by sea wave's action. This study aims predict impacts on this coastal area. Coastal stretches studied were Esmoriz-Furadouro Vagueira-Mira, due their vulnerability related with low lying sandy...

Climate change and global sea-level rise are major issues of the 21st century. The main goal this study is to assess physical biogeochemical status Ria de Aveiro lagoon (Portugal) under future climate scenarios, using a coupled physical/ eutrophication model. impact on ecosystem mean sea level (MSLR), amplitude M2 tidal constituent (M2R), changes in river discharge, rising air temperature was investigated. Under MSLR M2R, results point an overall salinity increase water decrease, revealing...

Salt marshes are among the most valuable ecosystems on earth; however, previous research has reported global losses in their extent accompanied by an impairment of ecological processes. Nonetheless, investigations salt marsh vegetation ecology still lacking many sites, including Ria de Aveiro. As such, this study aimed to (1) monitor, characterize, and understand evolution communities at three different sites with environmental conditions stages degradation, where we also sought (2) identify...

The interaction between tide, river runoff, and wind in coastal lagoons induces complex salinity gradients, which are remarkable when the meteorological forcing is exacerbated. This work aims to characterize structure under extreme freshwater events Ria de Aveiro lagoon (Portugal). Delft3D model was implemented validated 3D mode used perform simulations forced with scenarios. Results show that conditions determine stratification intensity location. Generally, increases as increases, while...

Coastal municipalities and industries often discharge poorly treated wastewater into proximate marine estuarine environments. The urban and/or effluent input can lead to eutrophication lower water quality, as it holds high concentrations of nutrients pollutants. One widely applied tool increase dispersion direct away from coastal areas, thus causing fewer impacts on human activities, is sea outfall. In Aveiro, Portugal, the São Jacinto outfall construction was completed in 1998; however,...
