One-Dimensional Wave-Current Interaction

J. M. Smith

This Coastal Engineering Technical Note (CETN) describes the theory and a computer program for calculating the wave height, wavelength, and wave steepness for monochromatic waves interacting with a uniform current for a one- dimensional channel. Ocean waves entering an inlet against an ebb current steepen (wave height increases and wavelength decreases) and can pose a hazard to navigation and dredging operations. On a flood current, wave steepness decreases (wave height decreases and wavelength increases). Design or modification of inlet channels requires consideration of wave-current interaction. Information presented in this Coastal Engineering Technical Note (CETN) may assist engineers in understanding and quantifying navigable conditions at existing inlets, and in making modifications to channels and jetties that might alter the current and waves in the entrance channel.
