scooping out a channel bed to prevent accumulated silt from stopping ship traffic.

removal of sediment from the bottom of a sea or river. Carried out to improve navigation or to obtain material for construction uses and beach nourishment.

Dredging is the act of digging out or removing material from an area, channel or throughway, such as the scooping of sediment deposits within a riverbed.

Cleaning, deepening, or widening of a waterway, using a machine (dredge) that removes materials by means of a scoop or a suction device.

Dredging is the process of removal of mud from the bottom of water bodies. Environmentalists claim the process of dredging can disturb the ecosystem and can cause silting that kills aquatic life. Prop [..]

The removal of sediment or the excavation of tidal or subtidal bottom to provide sufficient depths for navigation or anchorage, or to obtain material for construction or for beach nourishment. Dune

a fishing method that involves a heavy frame with an attached net that is dragged along the sea floor; dredging can cause serious damage to the sea floor and benthic habitats.

Excavation under water to gather up bottom sediment. Dredging is often necessary during building and maintenance of barrages.

Removal of sediment to deepen access channels, provide turning basins for ships, and maintain adequate water depth along waterside facilities.

Underwater excavation activity or operation with the purpose of gathering up bottom sediments and disposing them at a different location. Sediment that has been dredged from the waterway is called dredged material or dredge spoil.

Excavation or displacement of the bottom or shoreline of a water body. Dredging can be accomplished with mechanical or hydraulic machines. Most is done to maintain channel depths or berths for navigat [..]

Dredging is the removal, displacement, or disposal of unconsolidated earth material such as sand, silt, gravel, or other submerged materials, from the bottom of water bodies, ditches, or natural wetlands; maintenance dredging and/or support activities are included in this definition.

Removal of mud from the bottom of water bodies. This can disturb the ecosystem and causes silting that kills aquatic life. Dredging of contaminated muds can expose biota to heavy metals and other toxi [..]

The removal of materials including, but not limited to, rocks, bottom sediments, debris, sand, refuse, and plant or animal matter in any excavating, cleaning, deepening, widening or lengthening, eithe [..]

Manoeuvring a vessel in a tideway by dragging an anchor on bottom and using difference in speed, between rate of current and speed over ground, for steerage purposes.

The scooping, or suction of underwater material from a harbor, or waterway. Dredging is one form of channel modification. It is often too expensive to be practical because the dredged material must be disposed of somewhere and the stream will usually fill back up with sediment in a few years. Dredging is usually undertaken only on large rivers to m [..]

An excavation operation necessary to maintain appropriate water depths for the safe navigation of ships. This activity is usually carried out by scooping or suctioning of sand and mud deposited by water currents into the navigation channels.

The scraping of the ocean floor by commercial fishermen to collect up sea bed dwelling sea life.

The removal of sediment from the bottom of a river or sea, often undertaken to improve navigation or to obtain material to use elsewhere.
