Q

Rock groynes

A

Stop LSD and builds up a wide beach

Stop sedimentation of harbour entrance so enables shipping lanes to keep open

Ecological benefits bc they are colonised by algae and lichens then crabs and other life forms. Improved diversity and key part of succession

Land would erode back 1.6m a year if not for groynes causing bechs to absorb wave action

However, computer modelling shows little difference in cost between beach replenishment and groynes
