Random waves are often expressed as a mathematical superposition
of an infinite number of sinusoidal components. The mean square spectral
density of the water surface elevation is often called the wave spectrum.
The zero upcrossing wave heights usually have a Rayleigh probability
distribution. However, the design wave concept is still...
