Dredging. What is Dredging? Definition and Purpose
Dredging is a process that involves
the aquatic excavation of water beds to remove sediments, pollutants,
shellfish and other materials. The methods and machinery used in
dredging vary widely. Most dredging is done by ships that tow a dredge
along the water bed. Self standing dredges and dredge pumping stations
are used for routine tasks. A dredge, which is the catch all term for
the different types of machinery that perform dredging, can cut away
sediment, scoop materials out like a back hoe or suction them through a
large pipe to be deposited into a ship, barge or other containment
system.
Dredging. What is Dredging? Definition and Purpose

Dredging serves four general purposes:

 

1) Dredging is
preformed to create or deepen waterways to allow large ships to pass.
Throughout time, waterways become filled with silt and sediment which
require fairly general maintenance in order to be efficient. With ever
expanding markets, there is also a demand for the creation of new
waterways.
2) Dredging is used to catch seafood. This type of
dredging involves dragging a metal mesh net along the bottom of the
ocean floor or other large body of water to catch animals such as crabs,
fish and squid.
3) Dredging is performed in the attempt to remove
pollutants and invasive species of plants from a particular body of
water, although this practice is controversial. Removing pollutants this
way often causes other environmental problems such as the destruction
of habitats of important plant and animal species.
