Maintaining waterways and harbors is important. Silt and other debris naturally works its way down into rivers, canals, channels, and harbors and collects. As it collects, it raises the bottom of the waterway. That will change the depth of that particular waterway. That can make it so it is less navigable, keeping out certain ships. When that happens, the area needs to be dredged. Dredging involves using a dredger that can clear away all the silt and the debris on the bottom of the waterway.
