Abstract:In the UK, particularly in southern and south-eastern parts of England and in South Wales, sand and gravel dredged from the offshore seabed makes an important contribution to the aggregate needs of the construction industry. In addition, sediments from the seabed have been used to carry out numerous hydraulic fill schemes for important industrial or commercial development, and to supply beach recharge schemes. Marine aggregate dredging also reduces the need for new inland sand and gravel pits, which are rarely popular developments. In addition, the use of large dredgers not only to collect but also to transport large quantities of sand and gravel, often delivering them to wharves in major cities, reduces heavy goods vehicle movements and reduces the costs of transport of these very bulky materials. Despite these advantages, there are very few other marine activities that engender so much concern about their possible adverse impacts, not only in and close to the dredging areas but also further afield. This keynote lecture reviews the continuing debates about and research into the environmental effects of marine aggregate dredging, with particular emphasis on the potential changes along or close to coastlines. Keynote presented at the Young coastal scientists an engineers conference in March 2010.
