Wooden sticks on the beach. They lower the force of the waves when they hit the coast. The
trap sand and pebbles so that they cannot be taken away by longshore drift. They make a

Pro: relatively cheap compared to
other methods
Con: It means that places further

smaller beach because the
groynes are holding all the sand in
one patch of the beach
Concrete Sea Walls:
Large concrete walls, normally along promenades (walkways along the beach). They are
curved at the top in order to force the wave backwards into the sea.
Pro: They’re effective – water cannot get through them and erode
Con: They’re very expensive and don’t always look nice
Gabions:
Gabions are steel wire cages filled with stones. They are then stacked on top of each other
where they act like a sea wall.
