Model equations

The wave height is modelled by the equation:

\[ \eta = \frac{H}{2} \cos (k x -\omega t + \phi) + k \frac{H^2}{4} \frac{3 - \sigma^2}{4 \sigma^3} \cos \left(2(k x - \omega t + \phi)\right) \]

where:

\( H \)	=	wave height
\( k \)	=	wave number
\( \omega \)	=	angular frequency
\( \sigma \)	=	radian wave frequency
\( \phi \)	=	phase shift
\( t \)	=	time
