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

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

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.
