Sensitivity assessment of wave heights to surface forcing in Cook Inlet, Alaska

► We perform a sensitivity study of wave heights to surface forcing in Cook Inlet. ► We examine wave-current interaction using two coupling approaches (one- & two-way). ► Effect of current on waves is more pronounced for smaller wave heights (<2 m). ► Effect of waves on current is found to be negligible. ► We conclude that one-way coupling would be adequate for wave forecasting purposes.
