Coastal erosion removes material from the shoreline and redistributes it to other parts of the coastal cell. While erosion is usually most drastic during extreme events with associated high surges and waves, shoreline erosion can also occur gradually over a longer time period due to sediment deficits.
This widespread erosion is due to a variety of factors, most notably:. Coastal erosion is a naturally occurring process that can be exacerbated and becomes a significant problem when the dynamic coastline impinges on the fixed human infrastructure and uses within the coastal zone.
Coasts continue to support the economic centers of the world, while at the same time critically ecologically important and sensitive natural habitats are supported by coastal zones. Coastal zones support a wide variety of human land uses.

Is the current coastal management sustainable? Houses and other buildings close to the shoreline are at a huge risk of being lost due to erosion of the land around them.
