The wave height is modelled by the equation:
\[ \eta = \frac{\lambda}{k} \cos (k x -\omega t + \phi) + \frac{(\lambda^2 B_{22} + \lambda^4 B_{24})}{\lambda} \cos\left(2(k x - \omega t + \phi)\right) + \frac{(\lambda^3 B_{33} + \lambda^5 B_{35})}{\lambda} \cos\left(3(k x - \omega t + \phi)\right) + \frac{(\lambda^4 B_{44})}{\lambda} \cos\left(4(k x - \omega t + \phi)\right) + \frac{(\lambda^5 B_{55})}{\lambda} \cos\left(5(k x - \omega t + \phi)\right) \]
where:
\( \lambda \) | = | first order wave amplitude |
\( k \) | = | wave number |
\( \omega \) | = | angular frequency |
\( \phi \) | = | phase shift |
\( B_{xx} \) | = | coefficients in the fifth order solution |
\( t \) | = | time |
