had removed the foredune and produced a large washover fan that extended inland
(Fig. 3.4). Over time, small hillocks formed on the washover feature and pioneer
vegetation extending onto the washover fan from the ends of the breached
foredune created an incipient foredune that extended for much of the breadth of the
fan (Fig. 3.5). The creation of this foredune is currently a bit farther inland than the
former foredune, and it is being established in response to the ambient processes,
sediment availability, and vegetation stabilization. The foredune form will likely
shift and change dimension through time as it responds to the ambient processes.
There is no equilibrium dimension to this foredune; only its natural presence on
the profile and its morphological response to the environmental drivers.
