Summary:

"Siltation is a continuous phenomenon that takes place in most of our ports and waterways. In order to guarantee the desirable water depths on a continuous basis it is necessary to carry out regular maintenance dredging. Especially for the smaller projects this means a heavy financial burden on the port management as dredging becomes generally spoken more efficient with increasing size of the port especially when using the more traditional dredging techniques. Water injection dredging (WID) is based on a concept that moves the sediment by using mainly natural forces present in the environment. This technique injects high quantities of water into the top layers of the underwater bottom in order to fluidise these layers and to create a density flow over the underwater bottom. In this way the sediments remain in the natural ecosystem and long lasting, cumbersome permit procedures can be avoided in some cases as the equilibrium of the ecosystem is far less disturbed because the sediment is just brought back to the ecosystems where they originates from."-- Introduction.
