Artificial island

An artificial island is a land area created or enlarged by people, usually by placing fill or structures in water. It can support settlement, infrastructure, industry, or coastal protection.

Land reclamation: The creation of usable land by filling or draining areas that were previously underwater or marshy. Artificial islands are commonly built by depositing fill in shallow water.
Palm Jumeirah: An artificial archipelago in Dubai, United Arab Emirates, shaped as a palm tree and developed for tourism and housing. Its engineered shape and resort development exemplify high-profile coastal reclamation.
Offshore airport: An airport located in water or on land constructed offshore, often to avoid space constraints onshore. Artificial islands provide stable platforms for runways near densely populated coasts.
Coastal erosion: The loss of shoreline material through waves, currents, wind, or human activity. Island construction can redirect currents and accelerate erosion on nearby coasts.
Dredging: The removal of sediment or other material from the bottom of a body of water. Dredging supplies fill and creates channels or foundations around reclaimed land.
Kansai International Airport: An international airport built on an artificial island in Osaka Bay, Japan. It demonstrates how offshore land can accommodate infrastructure where coastal sites are scarce.
Seaport: A coastal facility where ships load and unload cargo or passengers. Reclaimed islands can add deep-water berths and storage to crowded ports.
Marine habitat: A marine environment that provides the conditions and resources organisms need to live. Filling seabeds can bury habitats and alter the ecosystems around an artificial island.
Hydraulic fill: A mixture of water and sediment pumped through pipes and deposited to form or raise ground. Pumped sediment can build broad artificial-island platforms quickly.
Flevopolder: A reclaimed land area in the Netherlands that forms the largest artificial island by area. Its scale shows how reclamation can create entire regions, not just small sites.
