Journal of Coastal Research, 29(6), 1309-1325. Coconut Creek (Florida), ISSN 0749-0208.A wave-prediction system based on spectral models was validated against in situ measurements in the Portuguese continental nearshore and is now operational. As a final extension of this system, the present article describes the implementation and validation of high-resolution wave models. In this connection, the objective of the present work was to evaluate the performance of such models in different coastal environments. The first target was an open coastal area located in the central part of the Portugal continental. An evaluation of the two state-of-the-art phase-resolving wave models, REFDIFl and FUNWAVE, was carried out, and the results are compared with those from a field experiment. The second target area was the port of Leixöes in the north of the Portuguese continental coast. A high-resolution SWAN computational domain that included the harbor area, was implemented and connected to the modeling system that provides ocean forcing. To provide a more realistic picture of the wave conditions inside the harbor area, the FUNWAVE model was also coupled to the wave-prediction system. Comparisons between the results provided by the two wave models provide a hetter image of the reliahility and limitations of both models at the entrance and inside the harhor area.Ocean waves, numerical models, high resolution models, coastal environment, harbor ADDITIONAL INDEX WORDS: areas.

“…Short-crested irregular waves with s = 10 and s = 75 have been, here, considered to represent wind and swell seas, respectively. The selection of the irregular short-crested wave conditions is based on research findings by Troch et al (e.g., [2]) and Beels et al (e.g., [1,29,30]). Short-crested irregular waves have been generated with wave propagation angle, θ = 0°.…”

Abstract:Experiments have been performed in the Shallow Water Wave Basin of DHI (Hørsholm, Denmark), on large arrays of up to 25 heaving point absorber type Wave Energy Converters (WECs), for a range of geometric layout configurations and wave conditions. WEC response and modifications of the wave field are measured to provide OPEN ACCESSEnergies 2014, 7 702 data for understanding WEC array interactions and to evaluate array interaction numerical models. Each WEC consists of a buoy with a diameter of 0.315 m and power take-off (PTO) is modeled by realizing friction based energy dissipation through damping of the WEC's motion. Wave gauges are located within and around the WEC array. Wave conditions studied include regular, polychromatic, long-and short-crested irregular waves. A rectilinear arrangement of WEC support structures is employed such that several array configurations can be studied. In this paper, the experimental arrangement and the obtained database are presented. Also, results for wave height attenuation downwave a rectilinear array of 25 heaving WECs are presented, for the case of irregular waves. Up to 16.3% and 18.1% (long-crested) and 11.2% and 18.1% (short-crested waves) reduction in significant wave height is observed downwave the WEC array, for the radiated wave field only and for the combination of incident-diffracted-radiated (perturbed) wave field, respectively. Using spectra at different locations within and around the array, the wave field modifications are presented and discussed.

“…Communication and interaction between the WGs will ensure the targeted integrated techno-economical approach of wave energy in Europe (interaction between hydrodynamics, array optimization, concept and PTO optimization, economics, policy, legislation, etc.). WG1-Numerical hydrodynamic modelling for WECs, WEC arrays/farms and wave energy resources (accuracy, uncertainty, coupling, applicability, usability): For evaluation of wave energy resources and site characterization, and for studying far-field effects of WEC arrays/farms, typically wave propagation models are employed (e.g., in [28][29][30]), while for studying WECs and their near-field effects, wave-WEC interaction solvers (e.g., in [31,32]) are used (e.g., based on boundary element methods (BEM), computational fluid dynamics (CFD), etc.). Nowadays, coupling techniques are also used between wave propagation models and wave-WEC interaction solvers [33,34].…”

Growing energy demand has increased interest in marine renewable energy resources (i.e., wave energy, which is harvested through wave energy converter (WEC) arrays. However, the wave energy industry is currently at a significant juncture in its development, facing a number of challenges which require that research re-focuses on a holistic techno-economic perspective, where the economics considers the full life cycle costs of the technology. It also requires development of WECs suitable for niche markets, because in Europe there are inequalities regarding wave energy resources, wave energy companies, national programs and investments. As a result, in Europe there are leading and non-leading countries in wave energy technology. The sector also needs to increase confidence of potential investors by reducing (non-)technological risks. This can be achieved through an interdisciplinary approach by involving engineers, economists, environmental scientists, lawyers, regulators and policy experts. Consequently, the wave energy sector needs to receive the necessary attention compared to other more advanced and commercial offshore energy technologies (e.g., offshore wind). The formation of the first open pan-European network with an interdisciplinary approach will contribute to large-scale WEC array deployment by dealing with the current bottlenecks. The WECANet (Wave Energy Converter Array Network) European COST Action, introduced in September 2018 and presented in this paper, aims at a collaborative and inclusive approach, as it provides a strong networking and collaboration platform that also creates the space for dialogue between all stakeholders in wave energy. An important characteristic of the Action is that participation is open to all parties interested and active in the development of wave energy. Previous activities organised by WECANet core group members have resulted in a number of joint European projects and scientific publications. WECANet’s main target is the equal research, training, networking, collaboration and funding opportunities for all researchers and professionals, regardless of age, gender and country in order to obtain understanding of the main challenges governing the development of the wave energy sector.
