ocean tide and amplification of the bay tide could occur. This will be seen in King's solution also (and can
be noted in Figure II-6-18 where the bay-ocean tide ratio is greater than one). King defines the dimensionless
velocity as:

where Vm is the maximum cross-sectionally averaged velocity during a tidal cycle. (To determine Vm , use
Equation II-6-5 and refer to Figure II-6-19.) Two parameters are calculated with the variables defined
previously.
