Sand motor

Shore nourishment or beach nourishment — also referred to as replenishment — is a maintenance measure by which sediment from outside the area is added to a (usually eroding) shore. A wider beach or a higher foreshore can reduce dune erosion or storm damage to coastal structures by dissipating energy across the surf zone. Shore nourishment is typically part of a larger coastal maintenance strategy. It is usually a repetitive process, since it does not remove the physical forces that cause erosion: It just mitigates their effects. Regular beach nourishment, i.e. placing a relatively small amount of sand at the moment it is needed in line along the shore or on the beach, has the disadvantage of frequently disturbing the coastal ecosystem. To avoid this disturbance and at the same time make new room for environmental processes, different types of beach nourishment are proposed, in which the sand volume is not just placed in line along the beach or the foreshore.

Large concentrated sand deposits on the foreshore,

intended to gradually feed the adjacent shore via

the natural forces working on it.

An artificial beach fill, extending from the shoreline

down into the foreshore, where a submerged stable

sill or dam is placed to support the lower part of the profile.

A seabed with large-scale bedforms (sandwaves)

comes with more biomass and a higher biodiversity

than one without bedforms.
