Calculate Morison's equation ocean wave velocity and acceleration from return period data using the Weibull, Gumbel or Frechet distributions.
The wave velocity and acceleration are calculated using either the Airy wave, Cnoidal wave or Stokes wave profile. Wave spreading accounts for the "choppiness" of the wave.
Enter data values as sets of three values separated by a comma (R, H, T), with each data set on a new line. Go to the bottom of the page to view the regression output.
