Therefore, a water injection dredger contains a series of nozzles located on a jetbar, which spray water. WID method involves water injection into the sediments.

While traditional dredging techniques are an effective solution for removal of accumulated sediments, it can be a costly process, especially for smaller ports and harbours. ![]() Therefore, regular maintenance dredging is necessary to maintain appropriate water depths and safe navigation.
