Abstract
Seagrasses have been demonstrated to be an effective attenuator of wave energy. However, the mechanisms by which waves are attenuated and the degree to which seagrasses physically respond to the passing of waves in a natural environment is poorly understood. The focus of this study was to quantify the attenuation of wave heights and the relative velocity of seagrass blades, measured as the difference in blade and water velocities, as waves progressed through a seagrass bed. An array of pressure transducers were deployed across the bed to measure wave heights while a video recorder and acoustic Doppler current meter measured water flow and blade movement form directly above. Results showed that the attenuation of wave heights across the seagrass bed followed an exponential decay model, but only after inducing wave shoaling at the entry to the bed. The relative velocity of the individual blades was shown to vary temporally and spatially, and was frequency dependent.
