What effect does dredging have on coastal erosion?
It is sometimes claimed that dredging causes coastal erosion, or makes it worse, as it has in the past. Various studies have recently been carried out to assess whether dredging makes surrounding areas more prone to erosion or not. Research results, such as those from the Southern North Sea Sediment Transport Study, shows that because dredging is now strictly controlled and carefully managed in UK waters, it no longer has an impact on coastal erosion. A licence is required for dredging. Thorough assessments are carried out to ensure dredging will not have a negative impact on the coastline or the marine environment before a licence is granted. Marine dredging licences are administered by the Marine Management Organisation.
