Beach nourishment can be defined as:
“The replacement of sediment lost from a section of beach using either beach recharge, recycling or bypassing, or any combination thereof.”
Beach Recharge - Material is sourced from outside the normal beach sediment system and introduced to the littoral system.
Beach Recycling - Material is sourced from downdrift in the littoral system and returned to the nourished beach.
Beach Bypassing - Material is sourced from updrift in the littoral system and moved on to the nourished beach.
There are three main scenarios in which beach nourishment is commonly used:
- In areas of coast experiencing loss of beach material and a shortage of incoming littoral drift;
- On any beach acting as a self-contained coastal cell but where redistribution of the beach material is occurring;
- For the purposes of enhancing or retaining the recreational value of the area by creating a wider beach, or following land reclamation such as the construction of a promenade, a similar beach further seaward.
- Split bottom barges
- Pipeline (“sinker”)
- Rainbowing / Trickling
