Key infrastructure facilities, including municipal utility buildings and residential structures, are located in the
backshore of Iqaluit's main beach.
All the beaches have narrow
backshore and are devoid of dunes.
Esta migracion, y consecuente retroceso de la linea de costa, causa erosion en las playas posterior y anterior (
backshore y foreshore) y deposicion en las playas interior y exterior (inshore y offshore).
In the Willandra this pattern is apparent when stone artefact assemblages from the lake foreshore are compared to those from the
backshore (Hiscock and Allen 2000) and such continuity is not unique to Australia.
-- Seasonal variation in vegetative cover, species richness, species composition and species importance were compared in the
backshore and primary dunes topographic zones at a dune protection area and an unprotected site on South Padre Island, Texas, from May 2004 to April 2005.
Dunes weren't needed for protection in this area because of the naturally high
backshore, so they weren't included in the Corps's project.
Due to continuing submergence, a small section of
backshore, previously too high to have been exposed, becomes subject to wave action.
The reverse is theoretically true; the beach profile will migrate downwards and lakeward in response to accretion of beach grade sediment in the
backshore through landward transport of near-shore bottom sediment.
In the 1980s, the diversity of plant species on the
backshore and primary dunes was declining.
