Artificial Island Construction Methods, Design and Advantages
Dredge up sediment in a shallow sea and deposit it wherever you want your island to be. Continue until it is a nice shape and height. Remember tides and storms, and make sure your island is high enough to survive a storm surge. Get a supply of good organic-rich topsoil and plant salt-resistant grass. Sep 15, · Island builders take the sand and rock and deposit it atop the existing reef base. One advanced technique called rainbowing, which has been utilized in .

By Katharine Gammon August 06, With an average elevation of just five feet above sea level, the Maldives—a nation comprising 1, islands in the Indian Ocean—is the lowest country in the world. Sea level, meanwhile, has risen by about seven inches sinceand scientists predict that it will rise as much as two more feet bypushing much of the population about what is corporate strategy definition, and growing out of their homes.
In the past, engineers have used sand and rubble to create islands elsewhere, but these structures can disturb the sea and seafloor ecosystems. In the Netherlands, the company has already built floating islands for prisons and housing from slabs of concrete and polystyrene foam.
For the Maldives, it will anchor similar structures to the seabed using cables or telescopic mooring piles, making landforms that are stable even in storms. The design disturbs only a small patch of the seafloor while preserving natural currents.
And many smaller islands are more ecologically sound than one large one because they cast smaller shadows on the water, minimizing the impact on sea life. Although the company is starting to build an island for luxury residences and another for a floating golf course this year, it is working on plans to construct islands for more affordable housing next.

Jul 16, · First, you’d have to locate your country-to-be outside of everyone else’s mile maritime Exclusive Economic Zones (EEZs). For reference, the areas open for development are those in white. Next, you’d have to build your island. A major difficulty is that all those white areas are in deep — very deep — water.
All around the world, cities are edging further into the sea. Plans are afoot to build huge islands and giant constructions in coastal areas, featuring the dredging and dumping of million of tonnes of material. What are the implications for ocean life and ecosystems as we build more and more into the ocean?
Cities have been creeping further into the ocean ever since we first starting building harbours. Almost every coastal province in China has projects underway to build out the coastline, either by dumping soil from the mainland, dredging it up from further out to sea, or by blocking river estuaries and allowing the silt to build up. But it is Dubai that is home to perhaps the most famous of reclaimed areas.
Its visually spectacular and entirely artificial Palm Jumeirah archipelago, home to the obscenely wealthy, is built from an estimated million cubic metres of dredged sand. And as one of the most densely populated nations on Earth, the low-lying Netherlands has long been driven to reclaim large swatches of its coastal swamps and marshes to house its ever-growing population. Building into the sea can cause havoc for ocean ecosystems Credit: iStock. For ocean ecosystems, certainly.
Even more minor coastal constructions can transform the seas. Reclaimed land is also a risk in earthquake-prone areas. The prolonged shaking can trigger a process called liquefaction, where the once-solid sediments of reclaimed areas can liquefy.
This was a significant contributor to the devastation of the huge San Francisco earthquake of Given that land reclamation tiptoes the line between earth and sea, disputes over sovereignty keep lawyers of both very busy indeed. While China has claimed sovereignty over these new islands, numerous countries — including the US and Australia — do not acknowledge this. In July this year, the International Court of Arbitration in The Hague also ruled that China had no historical claim to the region but sabre-rattling continues and there is no sign of an agreement on the horizon.

Similarly in Perus Lake Titicaca, the Uros people live on floating islands made from bundles of reeds. Around the world, architects are building more modern floating homes, especially in countries such as the Netherlands which is vulnerable to flooding. This gets into somewhat more fanciful territory. Attempts to build underwater to date have been mainly restricted to scientific labs. One of the earliest underwater habitats was set up in by Jacques-Yves Cousteau and his team.
They followed it up with a small village on the floor of the Red Sea that was occupied for a month, and eventually Conshelf III, built one hundred metres below the surface near Nice in France in , home to six oceanauts for three weeks at a time. And Florida International University still operates a lab called Aquarius , nine kilometres off Key Largo, with space for six researchers, a kitchen and a laboratory space.
There are signs of more luxurious undersea properties coming soon though. If you liked this story, sign up for the weekly bbc. World-Changing Ideas Oceans.

By Bianca Nogrady 1st November As urban areas get more crowded, building new land and even floating homes is becoming more economic — but is it storing up future problems?
