Amw versus ebb-tidal delta area (AED) (Vincent and Corson 1980)
(f) Inlet channel flow area is constant.
(g) Inertia of the mass of the water in the channel is negligible.
(2) Some assumptions may seem stringent (e.g., assumption (e), which essentially assumes a frictionless
bay). This could be a problem if the entire bay is composed of very shallow tidal flats with no significant
channelization. Also, in assumption (f), a relatively large tidal range compared to channel depth might
occur. However, reasonable results can be determined for most cases. For more complex inlet systems, more
sophisticated modeling should be performed, as discussed earlier.
(3) The one-dimensional equation of motion for flow in the channel is:
