(4) Keulegan neglected local acceleration (the first term in Equation II-6-2) and integrated the equation

over the length of the inlet. Using the equation of continuity for flow through the inlet into the bay:

(II-6-3)

where

(5) Combining Equations II-6-2 and II-6-3, Keulegan developed a solution for velocity and resulting bay

tide which contained the dimensionless parameter K, known as the coefficient of repletion, or filling, which

is defined as

2*g*

(II-6-4)

2 π *A*b

4*R*

where *A*avg, AB , g, f, and *R *are as defined above, and
