“…Previous wave model comparisons remain primarily dedicated to the performance evaluation for predicting wave parameters like the significant wave height, the peak period or the mean direction (e.g., Bidlot et al, 2002;Strauss et al, 2007;Rusu and Guedes Soares, 2011). The present study extends these comparisons to differences obtained in wave power predictions.…”

“…In the present study the wave model was set up to account the following wave processes: shoaling, refraction due to current and depth, whitecapping, bottom friction and depth induced wave breaking [56]; using two computational grids with different resolutions ( Fig. 2): (i) an offshore grid covering an area of approx.…”

Coastal defence using wave farms: The role of farm-to-coast distance

a b s t r a c tThe location of a wave farm and, in particular, its distance to the coast is one of the key aspects in a wave energy project. The effects of the farm on the coast, which can be instrumental in mitigating storminduced erosion and thus contribute to coastal defence, are sometimes disregarded in selecting its location, possibly due to the inexistence of an ad hoc methodology. In this context, the objective of this work is to examine the influence of the farm-to-coast distance through a sensitivity analysis in a case study: Perranporth (UK). The impacts of a wave farm on the beach morphology are examined in four scenarios with different farm-to-coast distances using a high-resolution suite of numerical models. The results show that a wave farm closest to the beach offers the highest degree of coastal protection (up to 20% of beach erosion reduction). The downside of this enhanced coastal protection is that the wave resource available at this location would be slightly smaller (approx. 10%) than in the case of the wave farms further from the coast. More generally, we find that the farm-to-coast distance is a critical variable in determining the effectiveness of a wave farm for coastal defence.

“…This system was subsequently focused on the most relevant coastal areas, such as the Portuguese harbours [19,20]. At the same time, extended validations have been carried out against nearshore in situ measurements [21,22]. The tide influence was also considered in some high-resolution computational domains [23].…”

The wave energy in a shallow water location is evaluated considering the influence of the local tide and wind on the wave propagation. The target is the coastal area just north of the Portuguese city of Peniche, where a wave energy converter operates on the sea bottom. A wave modelling system based on SWAN has been implemented and focused on this coastal environment in a multilevel computational scheme. The first three SWAN computational belonging to this wave prediction system were defined using the spherical coordinates. In the highest resolution computational domain, Cartesian coordinates have been considered, with a resolution of 25 m in both directions. An in-depth analysis of the main characteristics of the environmental matrix has been performed. This is based on the results of eight-year model system simulations (2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012). New simulations have been carried out in the last two computational domains with the most relevant wave and wind patterns, considering also the tide effect. The results show that the tide level, together with the wind intensity and direction, may influence to a significant degree the wave characteristics. This especially concerns the wave power in the location where the wave converter operates.
