Calculate the dimensionless Ursell number.
The Ursell number is a measure of the non linearity of ocean waves.
`Ur = h L^2 / d^3 = (h/d)^3 / (L/d)^2 `
where :
Ur = Ursell number h = wave height L = wave length d = water depth
The Airy wave is suitable for Ur < 1. Stokes wave should be used for Ur < 40. Cnoidal wave should be used for Ur > 40.
