ABSTRACT This paper presents the results of an analysis carried out to determine the characteristics of waves during the transitional process from intermediate to shallow water off the Isle of Lewis in Scotland. Wave data acquired by a combined wave buoy and ADCP network across an area of approximately 25km x 15km is used for this study which includes three directional wave buoys deployed in 60m depth and two bottom mounted ‘wave enabled’ ADCPs in 12m depth. The study area is targeted for the extraction of wave energy and hence the data analysis concentrates only on the aspects of proportional variation of wave height, energy period and corresponding wave power over a one year period. The results indicate that local shoaling and refraction plays a major role in altering the wave properties and wave power for this region and this is further quantified and discussed in details.
