Rainbowing

The rainbow installation pumps a mixture of sand and water from the hold through a jet nozzle on the bow using a high-pressure pump. This makes it possible to propel the sand mixture over a distance of approx. 65 metres.

Using different nozzles, the size of the jet of sand mixture can be adjusted as required.

This so-called rainbowing technique is used for beach and shoreface nourishment.
