Calculate combined ocean wave and current velocity and acceleration for Airy, Stokes and cnoidal waves.
Wave length can be calculated from wave period, or wave period can be calculated from wave length. Current velocity can be calculated near the seabed using either the logarithmic profile, or the 1/7th power law profile. The velocity and acceleration can be calculated at either the wave surface (varies with phase angle), the wave trough height, the seabed, or at a user defined height above the seabed. Use the Result Plot option to plot the wave profiles, wave velocity or wave acceleration versus phase angle.
