Glossary
Blowout A saucer-, cup-, bowl-, or trough-shaped depression or hollow formed by
wind erosion in a pre-existing sand deposit. The adjoining accumulation of
sand, the depositional lobe, derived from the depression, and possibly other
sources, is normally considered part of the blowout landform.
Established Foredune Evolves from an incipient foredune, and either occupies
the seaward-most position at the rear of the beach or is situated behind an
incipient foredune. It is commonly distinguished by the growth of intermediate,
sometimes woody, plant species, and by its greater morphological complexity,
height, width, age, and geographical position.
Foredune (or fore-dune) A shore-parallel dune ridge formed on the backshore by
aeolian sand deposition within vegetation.
Foredune plains Comprise two or more (typically more) former foredunes. They
are formed where progradation has resulted in the multiple formations of
foredunes and swales over time.
Incipient foredune A new or developing foredune that forms by aeolian sand
deposition within pioneer plant communities.
Parabolic dune Also termed U-dunes, upsiloidal dunes, and hairpin dunes.
Typically U- or V-shaped dune, characterized by short to elongate trailing
ridges that terminate downwind in U- or V-shaped depositional lobes.
Relict foredune A stable, non-accretionary, former foredune that has become
isolated from accretionary or erosional processes by the seaward formation of a
new foredune. In some cases, a relict foredune has been termed a ‘‘beach ridge.’’
Transgressive dunefield Aeolian sand deposit formed by the downwind or
alongshore movement of sand over vegetated to semi-vegetated terrain. Such
dunefields may range from quite small (hundreds of meters in their alongshore
