Beach nourishment programs, which aim to replenish beach sand with sediment from offshore or an upland source, have become common in coastal communities worldwide. Beach nourishment involves using sediment to enhance dunes, the beachfront, and/or the shoreface. The sediment may be spread by machine and then moved by waves, tides and wind. This approach is best suited for low-lying oceanfront areas with existing sources of sand and gravel.
On the US eastern and southern seaboards, beach nourishment is used to replace sand lost to storms and protect against future erosion of the natural dunes and original shoreline. Nourishment projects require coastal modelling to be effective.
