The Ovar coastline is characterized as one of the coastal areas with the highest vulnerability and risk of erosion in the Portuguese coast. The high-energy coast is further threatened by a permanent sediment deficit of anthropic origin, as well as sea level rise due to climate change. It is essential to define modern coastal adaptation strategies t...

Nowadays there are numerous computational tools to forecast the evolution of the shoreline position in sandy coast environments. However, few studies have waited for the time horizon of the predictions to actually check the accuracy of the forecasted scenarios. Thus, this work proposed to assess the accuracy of medium-term predictions made with Lon...

Beach nourishment represents a type of coastal defense intervention, keeping the beach as a natural coastal defense system. Altering the cross-shore profile geometry, due to the introduction of new sediments, induces a non-equilibrium situation regarding the local wave dynamics. This work aims to increase our knowledge concerning 3D movable bed phy...

Full-text available
Serious erosion problems related to significant negative sediments budgets in the coastal systems are referred worldwide. Artificial nourishments are a coastal erosion mitigation strategy that allow for a decrease in those negative budgets by adding sediment to the coastal system. Thus, it is essential to understand and adequately model the shoreli...

The coastal stretch between Vagueira and Praia de Mira, northern Portugal, is subject to high-energy wave conditions. At the same time, the shoreline is a main contributor to the local economy, extensively due to tourism. Despite the shoreline being currently protected by groynes, a better understanding of the hydrodynamics and the morphodynamics i...

Coastal regions are among the most productive and valued ecosystems in relation to their ecosystem services (Millenium Ecosystem Assessment 2005; Hattam et al., 2015). However, their degradation is dramatically growing due to the increase of human pressure on coastlines that can negatively impact or threaten marine habitats. The evaluation of poten...

Dredged material resulting from deepening and maintenance activities of the Aveiro Harbor inlet channel, northwestern coast of Portugal, has been used to mitigate the erosion trend recorded on nearby beaches (from Barra to Costa Nova Beach) through direct placement of sand by using standard dredge equipment. The disposal activities of dredged mater...
Conference Paper
Figueira da Foz jettied estuary-inlet undergoes important morphological changes in response to the high energetic wave climate of the North Atlantic Ocean. These changes generate shoaling problems at the inlet due to the formation of a submerged sandbar. Therefore, harbor administration normally performs coastal dredging operations to guarantee nav...

Coastal zones host between 15% and 40% of the world population, important residential, tourism and port infrastructures, and a wide variety of terrestrial, aquatic and coastal ecosystems. These built and natural capitals, corresponding services and associated values may be lost due to coastal erosion. Coastal erosion adaptation strategies are frequ...

A new methodology of climate change adaptation planning, integrating a strong dynamic and participatory component, was developed and tested in one of the most vulnerable coastal zones in Portugal (coastal stretch Barra-Areão, in the municipalities of Ílhavo and Vagos). The method, designated SWAP - Scenario Workshop & Adaptation Pathways, consists...
Conference Paper
Many coastal systems across the world include natural longshore multi-bar systems (e.g., along the Dutch coast, US coast, and Japanese). Particularly for such sites, a proper simulation of the bar berm material exchange is required to reproduce the seasonal behaviour of the beach profile in order to realistically describe the effects of the sedimen...

Beach fill design typically involves nourishing one or several of the following coastal features with sand: the dune, the beach berm, the active profile, and nearshore bars. The impact of varying the location, volume, and frequency of placing sand on an open beach is here explored by investigating the redistribution of the nourished sediment toward...

Several anthropogenic actions have been weakening sediment supplies to coastal areas, reducing the amount of sediments available on beaches and leading to a general and recurrent retreat of the shoreline position. As a consequence, different coastal defense interventions, oftentimes longitudinal revetments, have been established over the past decad...

Article
Groins interfere with coastal dynamics and sediment transport, leading to sediments accumulation at the updrift side, while at downdrift, the erosive process is anticipated due to the lack of sediments. To improve numerical modeling capacity to simulate the groins impacts, it is necessary to totally understand the shoreline evolution along time and...

Aveiro é uma das zonas de Portugal mais afetadas pela perda de território devido à erosão costeira. O litoral deste distrito, maioritariamente composto por praias arenosas, é exposto a um clima de agitação marítima muito energético, sendo, portanto, propenso a alterações morfológicas. Ações antropogénicas sobre o litoral contribuem também para a al...

The coastal zones management not only relies on a profound knowledge of the shoreline but also on a good as- sessment of morphodynamics, sediments transport and coastal interventions required. Many coastal studies, such as beach slope estimates, equilibrium beach profile definition or sedi- ment transport analysis, depend on the sediment grain size...
Conference Paper
To develop the port facilities at Aveiro, several engineering works were carried out, between 1802 and 2012, namely the breakwaters’ construction at the inlet and dredging operations to ensure navigability, which have affected the natural morphological evolution of the lagoon, and the adjacent coastline. This work focuses on the characterization of...

Cohesive sediment transport is not directly related to easily measurable parameters. Erosion and deposition properties are usually described by critical bed shear stresses, erosion rate coefficients and settling velocities. To improve the reliability of numerical models, these parameters should be determined from observations and experiments, eithe...
Conference Paper
The maritime public domain in Portugal is defined for each place, by the line corresponding to the maximum high tide of equinoctial spring tides, depending on the waves run-up under average waves heights conditions. This approach has created challenges and problems to the responsible entities, which are not solved yet. The choice of a specific stud...

Floods and shoreline retreat in coastal areas threaten many millions of people across Europe. Moreover, it is agreed that climate change can amplify the magnitude and frequency of flooding events and accelerate the shoreline retreat. The main goal of this work is to assess flood and shoreline retreat risk, and define adaptation strategies under pre...

Groins are cross shore structures built to promote shoreline stabilization. However, the specific impact of these structures on the wave conditions and velocity field nearshore (and hence, on sediment transport) is still poorly understood. Therefore, this study wishes to extend this knowledge using a numerical model, COULWAVE, previously validated...
