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 Corozal was a Scottish-built dredger used on the Panama Canal. The Renfrew-based firm of Messrs. Wm. Simons & Company won a US government tender for its construction in 1911. The vessel was launched in November 1911 and taken into US government service as the US Corozal. It was the most powerful dredger ever built at that time. The Corozal operated on the difficult Culebra Cut, deepening a channel excavated by hand and dynamite. It became the first ship to sail through the cut in December 1913, shortly before the canal opened to traffic. The Corozal was sold to the Arundel Corporation in 1926 and scrapped in 1956.
Het verjaagde water is a 1947 Dutch non-fiction novel written by A. den Doolaard, which gives an account of the recovery works to repair dike breaches after the October 1944 Inundation of Walcheren as part of operations by The Allies of World War II during Operation Infatuate. Researchers from Delft University of Technology have found high levels of historical accuracy in den Doolaard's descriptions of the events that took place, the methods used to close the dikes and the key people involved. Den Doolaard assigned pseudonyms to most of the main characters and organisations. The name A. den Doolaard is also a pseudonym, the author’s real name being Cornelis Johannes George Spoelstra Jr.
