The Palm Islands are artificial peninsulas constructed of sand
dredged from the bottom of the Persian Gulf by the Belgian company Jan
De Nul and the Dutch company Van Oord.The sand is sprayed by the
dredging ships, which are guided by DGPS, onto the required area in a
process known as rain-bowing because of the arcs in the air when the
sand is sprayed. The outer edge of each Palm's encircling crescent is a
large rock breakwater.
The breakwater of the Palm Jumeirah has over seven million tons of rock.
