The word "backshore" is not a correct word in English.
This is likely a mistake of "backshore," which means land that is located behind a beach and is protected from storms and erosion by sand dunes. For example, "The beach was particularly beautiful due to the backshore of sand dunes."
The foreshore, backshore, and beach ridge deposits in these areas consist mainly of sandy sediment.
The existence of a vegetation-free backshore is found to be important for the nucleation timescale of coastal dune generations.
This response is complicated locally, however, by the influence of a backshore river that alters spatial temporal patterns of both intertidal and supratidal erosion and deposition.
Seventy-seven outcrop sections were studied and thirty-one sedimentary facies identified in five depositional environments ranging from lower offshore to backshore.
Former foreshore deposits are mapped in dip-orientation beneath modern backshore regions using ground-penetrating radar, documenting the nature of beach progradation.
Loss of the linkage between the backshore and dune caused by shore-parallel walls need not prevent restoration of native vegetation typical of the more stable backdune environments.
A lag surface of coarse sediment formed by deflation on the backshore, resulting in a rate of aeolian transport <2% of the rate on the wave-reworked foreshore.
The fill on the backshore remained above the zone of wave influence over a winter storm season and was separated from the active foreshore by the scarp.
Following construction, natural accretion of sediment on the backshore is preferable as it facilitates sustained natural dune building, growth of vegetation, and habitat creation and reduces the need for further beach scraping.
This paper examines the multi-decadal evolution of a foredune and backshore river complex on a wave-dominated, drift-aligned coast at Wickaninnish Bay on southwestern Vancouver Island, British Columbia, Canada.
