2DH modelling and mapping of surfbeat-driven flooding in the shadow of a jettie...
Nahon, Alphonse; Fortunato, André B.; Oliveira, Filipa S.B.F.; Azevedo, Alberto; Henriques, Maria João; Silva, Paulo A.; Baptista, Paulo; Freire, PaulaNear 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-resolving or phase-average solvers for wave propagation. In between, surfbeat solvers, such as in XBeach, combine an affordable computational cost with the ability to generate and propagate the lon...
Multi-Hazard WebGIS Platform for Coastal Regions
Rocha, Miguel; Oliveira, Anabela; Freire, Paula; Fortunato, André B.; Nahon, Alphonse; Barros, José L.; Azevedo, Alberto; Oliveira, Filipa S. B. F.The combined action of waves, surges and tides can cause flooding, erosion and dune and structure overtopping in many coastal regions. Addressing emergency and risk management in these areas require a combination of targeted campaigns and real-time data that measure all phenomena at stake and can be used to develop comprehensive monitoring platforms. These monitoring platforms can support the development of pre...
Effects of climate change and anthropogenic pressures in the water quality of a...
Rodrigues, Marta; Rosa, Alexandra; Cravo, Alexandra; Jacob, J.; Fortunato, André B.Understanding how climatic and anthropogenic drivers will influence coastal lagoons is fundamental to guarantee their preservation and sustainability. The Ria Formosa (coastal lagoon, South coast of Portugal) is a very important ecosystem that supports diverse economic activities in the region. The 3D coupled hydrodynamic-biogeochemical model SCHISM was validated and used to assess the influence of climate chan...

A local-scale approach to estuarine flood risk management
Freire, Paula; Tavares, Alexandre O.; Sá, Luís; Oliveira, Anabela; Fortunato, André B.; Santos, Pedro P. dos; Rilo, Ana; Gomes, João L.; Rogeiro, JoãoNew challenges in flood risk management are raised by climate change and land-use development. These challenges are particularly complex in estuarine and coastal systems, where different hazard sources interact in a dynamic socio-economic context. This paper presents an innovative approach to support flood risk management in estuaries. The approach, developed at a local-scale basis, is applied in the case study...
Development of an oil spill hazard scenarios database for risk assessment
Boer, Sérgio den; Azevedo, Alberto; Vaz, Leandro; Costa, Ricardo; Fortunato, André B.; Oliveira, Anabela; Tomás, Luís M.; Dias, João M.The occurrence of oil spills in coastal regions may have catastrophic consequences on the environment and severe socio-economic impacts. This work presents a new methodology to evaluate the risk associated with oil spills in coastal zones and estuaries, and illustrates its application in a coastal lagoon (Ria de Aveiro, Portugal). A ranked list of the hydrodynamic scenarios under which oil spills are most likel...
Generating inundation maps for a coastal lagoon: a case study in the Ria de Ave...
Fortunato, André B.; Rodrigues, Marta; Dias, João M.; Lopes, Carina; Oliveira, AnabelaCoastal flooding due to storm surges combined with high tides causes a growing concern, and recent legislation requires that European Union countries develop inundation maps for the areas at risk. This paper describes the methodology to generate inundation maps and its application to the Ria de Aveiro, a coastal lagoon exposed to Atlantic storm surges that can exceed 1 m. The maps are based on the application o...
Numerical modelling of shoreline evolution in the Aveiro coast, Portugal – clim...
Pereira, Carla; Coelho, Carlos; Ribeiro, Alexandre; Fortunato, André B.; Lopes, Carina L.; Dias, João M.In the Northwest coast of Portugal, the shoreline evolution is leading to several problems, such as loss of territory and infrastructural damages, mainly caused by the sea wave’s action. This study aims to predict the impacts of climate change on the shoreline evolution in this coastal area. Coastal stretches studied were Esmoriz-Furadouro and Vagueira- Mira, due to their vulnerability related with the low lyin...
