Coastal engineering

structure constructed on coasts as part of coastal management or to protect an anchorage

thumb|A grab dredge Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger.

The term waterwolf is an example of zoomorphism, in which a non-li
