Morison’s Generalized Equation

The Morison generalized equation is an empirical formulation used for calculations of hydrodynamic loads on slender structures, i.e. slender versus wavelength and wave height. Morison’s equation can be used when the the wavelength is large relative to the diameter.

The drag and added mass coefficients are given, dimensional or nondimensional, on the Hydrodynamic force coefficients tab of the cross section.
