In situ near-shore wave resource assessment in the Fiji Islands

Directional wave measurements were carried out at two different near-shore locations in the Fiji islands with the help of an underwater pressure transducer - a Directional Wave Recorder. The primary site which is located in the west of the main island in Fiji has a moderate energy potential of 9.81 kW/m at a depth of 15 m. The second site which was the focus of past wave energy measurements was also studied and the new data along with previous measurements show high energy potential at this location. This site near Kadavu Island has a near-shore energy flux of around 28.78 kW/m at a depth of 18 m. The directional spread of the waves and the nature of their occurrence are presented. Additionally, the sea states during a category 2 tropical cyclone passing about 200 km from the measurement location are discussed.
