A process of removing or disturbing layers of sediment, primarily to clear channels and ponds of excessive sediments. Dredging is carried out in Louisiana to maintain navigable waterways. The LCA Program proposes the development of a process whereby the millions of tons of sediment dredged annually in Louisiana will be used beneficially in areas where sediments are needed.
An ocean bottom sampler that scoops up rocks and sediment as it is dragged behind a moving ship. It is usually a heavy metal container.
A type of gear used to harvest shellfish (oysters, mussels, clams, scallops). It usually consists of an oblong metal frame that sweeps along the ocean floor and sucks catch into an attached net bag.
A device used to scoop up and process gravel so that the gold may be separated from it. See Alaska Gold Dredges.
An apparatus or machine for lifting mud, sand, silt, and small boulders from the bottom of a stream or the bed of an arm of the sea. To excavate with a dredge.
any of various machines equipped with scooping or scouring devices used to deepen harbors and waterways, and in underwater mining
A vessel designed to remove material, such as sand and gravel, from the bottom of the sea or other water body. Synonym: dredger. To remove material, such as sand and gravel, from the bottom of the sea or other water body.
a power shovel to remove material from a channel or riverbed
search (as the bottom of a body of water) for something valuable or lost
remove with a power shovel, usually from a bottom of a body of water
a machine that scoops or suctions sediment from the bottom of waterways or is used to mine materials underwater
a metal framed basket with a bottom of connected iron rings or wire netting called a chain belly
a small waterborne craft used to plow the bottoms of rivers and harbors
a vessel designed to remove sediment from the bottom, generally for the purpose of widening and deepening ship channels
a "vessel" under the Longshore and Harbor Workers' Compensation Act
To clear out the mud and sediment from a wetland area subsequent to filling it.
a method of removing sediments from the bottom of a river or stream and thus deepening its channel.
to remove dirt, silt, etc. to deepen a waterway
a machine equipped with a continuous revolving chain of buckets, a scoop, or a suction device for digging out and removing material from under water.
a device which brings materials (sands, gravels, boulders) from the seafloor to the surface. Several types are possible, using either suction (pumps) or mechanical action.
a barge used for removing earth or silt making deep channels in waterways
(noun) A waterborne machine that removes unwanted silt accumulations from the bottom of a waterway. (verb) The process of removing sediment from harbour or river bottoms for safety purposes and to allow for deeper vessels.
to remove or scrape up sand, gravel, or other surface deposits that are covered with water
A type of fishing gear used to harvest shellfish off the ocean bottom. A dredge is essentially a metal "rake" that is dragged across the ocean bottom, scraping up shellfish in its path.
To deepen, widen or remove materials from harbors and waterways by means of various machines equipped with scooping or suction devices.
Earthen material that is dug from a channel or removed from the bottom of a water body, often to improve drainage.
1. (noun) The machine used to remove, by suction or scooping, sediment from the bottom of a water body. 2.(verb) To remove sediment from the bottom of a water body.
A dredge is a machine used for scooping or sucking goldbearing gravel from the riverbed. There are numerous types and sizes, ranging from the small, portable, compact models that can easily be operated by one man, to large barge-type dredges for clearing mud from harbour entrances. Next to hydraulic mining, nothing destroys the landscape faster than dredges.
a motorized device for vacuuming stream,creek and river bottoms for gold.
A mining process by which sand in a river bed or stream is scooped up from the bottom and minerals are extracted.
A device for mechanically removing layers of sediment, rock, debris, and sand from a waterbody. Used to clear channels and for cleanup work.
The act of cleaning, deepening, or widening harbors and waterways with a machine equipped with a scooping or suction device. This equipment is also called a dredge.
To clean, deepen or widen with a machine equipped with scooping or suction devices.
A method used to deepen harbors and waterways
a fishing method that utilizes a bag dragged behind a vessel that scrapes the ocean bottom, usually to catch shellfish. Dredges are often equiped with metal spikes in order to dig up the catch.
An apparatus used for sucking up mud, sand, rocks, etc. from the bottom of a body of water, as when deepening or clearing channel or harbors.
