Contructive wave
The wave that returns to the sea, always at 90 degrees due to gravity
Swash
Builds up the beach as the swash has energy to bring in sediment, but the backwash is weak so it gets left behind.
Fetch
Removes sediment from a beach as the backwash is strong enough to entrain particles and return them to the sea.
