dc.description.abstractAssessment of wave power potential at different water depths and time is required for identifying a wave power plant location. This study examines the variation in wave power off the central west coast of India at water depths of 30, 9 and 5m based on waverider buoy measured wave data. The study shows a significant reduction (~10 to 27%) in wave power at 9m water depth compared to 30m and the wave power available at 5m water depth is 20 to 23% less than that at 9m. At 9m depth, the seasonal mean value of the wave power varied from 1.6 kWm<sup>-1</sup> in the post-monsoon period (ONDJ) to 15.2kWm<sup>-1</sup> in the Indian summer monssoon (JJAS) period. During the Indian summer monsoon period, the variation of wave power in a day is up to 32kWm<sup>-1</sup>. At 9m water depth, the mean annual wave power is 6kWm<sup>-1</sup> and interannual variations up to 19.3% are observed during 2009-2014. High wave energy (>20kWm<sup>-1</sup>) at the study area is essentially from the directional sector 245-270° and also 75% of the total annual wave energy is from this narrow directional sector, which is advantageous while aligning the wave energy converter
