An artificial island is an island that has been man-made rather than formed by

natural means. They are created by expanding existing islets, construction on existing

reefs, or amalgamating several natural islets into a bigger island.

Early artificial islands can be floating structures in still waters, or wooden or megalithic

structures erected in shallow waters.

In modern times artificial islands are usually formed by land reclamation, but some are

formed by the incidental isolation of an existing piece of land during canal construction,

or flooding of valleys resulting in the tops of former knolls getting isolated by water.

Some contemporary projects are much more ambitious. Kansai International Airport is

the first airport to be built completely on an artificial island in 1994.

Dubai is home to some of the largest artificial island complexes in the world, including

the three Palm Islands projects, The World and the Dubai Waterfront, the last of which

The Israeli government is now planning for 4 artificial islands to be completed in 2013,

of the coasts of Tel Aviv, Herzliya, Netanya and Haifa. Each island will house some

20,000 people and bring in 10,000 jobs.
