Abstract
This study investigates the interactions of waves and tides at a wave farm in the southwest of England, in particular their effects on radiation stress, bottom stress, and consequently the effects on the sediment transport and the coast adjacent to the Wave Hub, the wave-farm. In this study, an integrated complex numerical modelling system is setup at the Wave Hub site and is used to study the effect of wave-current interaction on current circulation, bottom shear stress, as well as the impacts in the nearshore zone. Results show that tidal elevation and tidal currents have a significant effect on the wave height and direction predictions; tidal forcing and wind waves have a significant effect on the bed shear-stress, relevant to sediment transport; waves via radiation stresses have an important effect on the longshore and cross-shore velocity components, particularly during the spring tides. Waves can impact on bottom boundary layer and the mixing in the water column. Interactions between waves and tides at the Wave Hub site are important when modelling coastal morphology influenced by wave energy devices.
