Residual circulation in estuaries plays a crucial role in controlling salt intrusion, material transport, and ecosystem functioning, making its understanding essential for coastal management worldwide. Despite its importance, ...
Inundation maps are required for spatial planning. This paper describes the generation of inundation maps for
the margins of the upstream region of the Tagus estuary (Portugal). Maps are constructed separately for a
major ...

CONNECT provides a local, high-resolution, coastal monitoring service. It integrates model-based forecasts
and observations to provide physical and biogeochemical data on Portuguese estuaries. The service is
demonstrated ...

The inlet of the Óbidos Lagoon is a wave-dominated tidal inlet located on the Portuguese coast. It is known for its unstable behaviour, which often leads to erosion issues on its margin or to its complete closure. Over ...
During storm conditions, infragravity (IG) waves with periods between 25 s and 300 s can dominate the seasurfaceoscillations near the shoreline. Through processes like wave run-up, overwash and wave overtopping,
IG waves ...

O acesso marítimo ao Porto de Aveiro, apresenta problemas de navegabilidade que condicionam a entrada de navios de grande dimensão, em particular em algumas situações de maré e agitação marítima. Este estudo apresenta e ...
The geometric characteristics of sand waves in the main channel of the outer Tagus estuary are
investigated, using high-resolution surveys conducted in 2019 and 2020. The relationship
between bedform height and spacing ...

This report presents the methodology and results of a study of the sediment dynamics and potential medium-term coastline evolution induced by hybrid-type coastal protection solutions for the Langue de Barbarie and the city ...
A first characterization of greenhouse gases had been carried out to study their role and impact in a productive
transitional coastal system of the southern Portugal – Ria Formosa lagoon. To this purpose, the partial ...
The efects of climate change on the estuarine environment are not fully understood. In temperate regions, droughts are expected to increase in frequency and severity, due to lower precipitation, and the mean sea level is ...

O Programa de Monitorização das Dragagens da Zona Superior da Lagoa de Óbidos, promovidas pela
Agência Portuguesa do Ambiente, destina-se a acompanhar a evolução das condições hidrodinâmicas e da morfologia da lagoa. ...
O aprofundamento dos canais de acesso por dragagem, associado ou não à construção de
molhes e quebra-mares, tem sido uma característica da evolução dos portos nacionais nos
últimos 100 anos. Nesta comunicação, analisa-se ...

Near estuaries and harbours, submerged shoals and defence structures impact the exposure to overtopping. These
features may be accounted for in two-dimensional horizontal (2DH) numerical models, either based on phase ...
As inundações costeiras afetam anualmente milhões de pessoas em todo o mundo, com
grandes perdas socioeconómicas que irão aumentar face à subida do nível médio do
mar e ao aumento dos níveis extremos de água. A extensa ...
Mainland Portugal presents an extensive, diversified and complex coastal zone. This diversity gives rise to diverse geomorphologic features which support different densities of human occupancy and a range of land uses and ...
