Wave height calculation

For spectral wave simulations, both average wave height and root-mean-square (RMS) wave height are calculated using zero-crossing at each grid point. Significant wave height is evaluated using Goda’s (2000) formula:

(135)\[H_{1/3} = 4.004\sqrt{m_0}\]

where,

(136)\[m_0 = \frac{1}{t_2-t_1} \int^{t_2}_{t_1} \eta^2 dt\]
