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.
Bulldozers are used to create a gentle profile which is much more effective at absorbing wave energy and preventing further erosion.
