Rainbowing
Encyclopedia
Rainbowing is the process in which a dredging
ship propels sand that has been claimed from the ocean floor in a high arc to a particular location. This is used for multiple purposes, ranging from building up a beach to prevent erosion
to constructing new islands. The name is derived from the appearance of the arc, which closely resembles a brown-colored rainbow.
This technique was notably used extensively in the construction of the Palm Islands
