Beach Nourishment – The addition of new material to a beach artificially, such as the dumping of large amounts of sand or shingle
The beach was hungry for nourishment so the boat crew found a way to give it large amounts of sand.
Beach nourishment = Food for the beach
A dredging vessel can pump sand on to the beach. Vessels can scoop up to 100 metres below the seafloor and throw it onto the beach from 80 metres away.
The reasons for beach nourishment include:
- A wider beach can protect against storm damage.
- Tourism (visitors want sandy beaches).
- Enlarging a beach can help to protect eco-systems on the shore
However, there can be downsides. For instance, some marine life can be buried under the new material.
Sand can be sucked up and pumped onto the beach from the seabed.
