Dubai’s Palm Islands are the world’s largest man-made island clusters. Sometimes they are also called the eight wonder of the world. These are located at three different places across Dubai’s coast, namely Jumeirah, Jebel Ali and Deira. These islands, which are also known as The Palm Dubai or Dubai Palm are layered with rocks and sand upon a ten meter deep seabed. Sand meant for laying down these sites is obtained by dredging in the nearby sea. The Belgian dredging firm Jan De Nul and its Dutch counterpart Van Oord have been supervising the whole operation. Work is in an advanced stage in Jumeirah and Jebel Ali while it has also picked up in the Deira section.
Dredging ships propel sand over an area, which is decided by the coordinates of Differential Global Positioning System (DGPS). This process is called rain-bowing; the name is indicative of the arc which is created due to the falling sand here. Each Dubai Palm has a breakwater constructed at its periphery, which provides it a separation from the murky seawaters. These breakwaters are constructed by laying down several layers of rocks over the seabed by sea vessels. These vessels are called pontoons...
