The validity of two irrotational wave-current models are experimentally examined. The models are applied for linear surface gravity waves and approximate the shear current by a straight-line and by a uniform velocity over the water depth. For the case of waves on opposing currents the linear shear current accurately predicts the waves horizontal particle velocity. The two models yield almost identical results of wave particle velocities for the case of following currents, however the theoretical prediction is slightly higher (up to 7%) than the experimental data. The method of superposition was also examined and found to yield inaccurate results for the examined cases. Waves significantly modify the ambient current shear which affects the total estimated drag and lift forces exerted on marine structures.
