Beach Reprofiling – Changing the profile or shape of the beach
In order to understand "beach reprofiling" you need to remember what the word profile is:
Profile: An outline
The professional used a file (profile) and that changed his outline completely.
Beach profile refers to a cross-sectional trace of a beach at an angle of 90° to the sea.
Beach reprofiling is therefore changing the outline of the beach.
Note: It usually refers to the direct transfer of material from the lower to the upper beach or occasionally the transfer of sand down the dune face from crest to toe.
Re-shaping the cross-sectional profile of a beach in this way ensures it offers the maximum protective gradient and width against destructive wave action.
Bulldozers are used to create a gentle profile, which is much more effective at absorbing wave energy and preventing further erosion.
