The experiment was initiated with a relatively small pilot channel, which usu-
ally enlarged over time to an equilibrium area, i.e., an area that did not change
significantly after a certain period of time. Initially, only tidal currents were the
forcing function. However, for some tests, waves were generated after an equilib-
rium area was reached for the tidal-current-only condition, and testing continued
until a second equilibrium occurred.
The experiments also provided valuable information for future phases of the
study program on inlet stability. Appropriate equilibrium areas would be useful in
the design of future laboratory work concerning ebb and flood shoals, for
example.
