Beach nourishment adds sand or shingle to replace material removed by erosion. A wider beach absorbs more wave energy, reducing the energy reaching cliffs or coastal property. It also provides a larger recreational area, which may benefit tourism, without creating a large concrete barrier.

Paper 2
Adding sand or shingle to a beach to replace lost sediment and increase its protection against waves.
Revise: Human Impacts and Landscape Change at the CoastSoft engineering includes beach nourishment, planting vegetation and cliff drainage. Nourishment replaces beach material, vegetation helps stabilise sediment, and drainage reduces water build-up in cliffs. These approaches work more closely with natural processes, but they still need upkeep: waves can carry away newly added beach material.
