Coastal erosion may be exacerbated by offshore dredging, as both the roads infrastructure programme and construction industry are heavily dependent on supplies of marine aggregates. Sourcing aggregates from marine deposits is increasingly seen as a means to partially meet such demands. The full impact of offshore dredging is unknown but it is implicated in starving the coast of the sediment needed for beach building (Hubbard & MacGuire, 1997).
