-
designed to reduce wave energy or create a barrier between the land and sea so storm waves can't reach the cliffs
soft engineering
-
-
-
works with nature rather than against it, blends in with the environment and can improve it e.g. adding sand to beaches, doesn't interefere with processes elsewhere and affect other areas and is sustainable.

wave types
constructive waves
low waves that surge up the beach and "spill" with a powerful swash; carry and deposit large amounts of sand and pebbles and "construct" the beach making it more extensive; formed by storms often hundreds of kilometres away
destructive waves
formed by local storms close to the coast so "destroy" the beach; closely spaced & often interefere with each other producing a chaotic swirling mass of water; high and steep before plunging down onto the beach; powerful backwash explaining the removal of sand and pebbles and the gradual destruction of the beach
