(8) Figures II-6-18 through II-6-20 provide a means to determine the bay tide range and phase and
velocity in the channel. A sample problem is presented in Part II-6-2, paragraph d, where determining
important parameters is discussed.
(9) Since channel resistance is nonlinear, channel velocity and bay tide will not be sinusoidal (Keulegan
1967). Other effects such as a relatively large tidal amplitude-to-depth ratio through the channel and
nonvertical walls in the channel and bay may be important in causing nonsinusoidal bay tides (Boon and
Byrne 1981, Speer and Aubrey 1985, Friedrichs and Aubrey 1988). However, for a first approximation,
channel velocity over time is represented as
