Properties

• Regular waves

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

Default model coefficients
