A low Keulegan K inlet has the potential to expand its entrance channel cross-sectional area to
much larger size if it is made more efficient by dredging, adding jetty structures; or if a new more
efficient channel is created either by dredging, storm scour, or by natural breakthrough. The new
more efficient channel will produce higher water levels in the bay due to an increase in tidal prism
and potential scour until the equilibrium channel area is reached.
