WebThe mean wave height and period are the simplest statistical parameters to define. They are found in the usual way as: and . l J T =~I~ J j=I For the example data set in Table l, the mean wave height and period are found to be 2.4 meters and 7.0 seconds. An imaginary wave with this height and period could be used as the basis for design. WebSignificant wave period (average over highest 𝑁/3 waves) ... Mean zero up-crossing period .

WebThe statistical distribution of zero-crossing wave heights in Gaussian mixed sea states is examined by analyzing numerically simulated data. Nine different kinds of bimodal scalar spectra are used to study the effects of the relative energy ratio and the peak frequency separation between the low and high frequency wave fields on the wave height distribution. WebA wave spectrum describes the energy distribution among wave components of different frequencies of a sea state. Wave spectra can be obtained directly from measured data. …

One of the limitations of the zero crossinis the poor definition of wave period. g method For example, a swell with a dominant period of 10 seconds will suffer a reduction in Tz with a superimposed locally generated sea. Both cases may, however, have a similar effect on a ...
