This study examined the impact of a theoretical nearshore wave farm on Perranporth Beach’s profile using a wave propagation model (SWAN) coupled with a coastal processes model (XBeach). Wave data from a nearby coastal buoy was used to prescribe the boundary conditions for an array of 11 WaveCat WECs arranged in two rows. The wave buoy data were used in conjunction with hindcast data from WaveWatch III to validate the wave propagation model.
This research was carried out in the framework of the Atlantic Power Cluster Project, funded by the Atlantic Arc Programme of the European Commission.
Perranporth Beach, Cornwall, England, UK
To understand the impact of a wave farm intended for coastal protection on the beach profile.
This relatively small, theoretical array at Perranporth was shown to have a significant effect on reducing the erosion of the beach face and in the bar, indicating that wave farms may be useful as a coastal defense measure.
