Model equations🔗

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
