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...

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...
