What is Dredged Sediment Used For?

Dredged SedimentDredging’s most common purpose is maintenance: to deepen or maintain navigable waterways or channels, as well as maintain the holding capacity of reservoirs or lakes. In most cases, a cutter suction dredge or large trailing suction hopper dredge are the best apparatuses for the job. The purpose of dredging is to excavate sediment from a body of water and move the sediment to a different location.

Dredging is a part of land reclamation.

In capital investments, dredging is done to create a new harbor, berth or waterway, or to deepen a waterway in order to accommodate larger vessels. Where rock work needs to be done, the procedure includes drilling and blasting prior to the excavation work. Much dredging is performed in preparation for future bridges, the building of piers or docks/wharves, or to complete foundation work for other building projects. Around the world, dredging is a function of land reclamation. Sand, clay, or rock are excavated from the seabed and are utilized to create land at another location. This process is most often used for flood or erosion control. The purpose of beach nourishing is to mine sand offshore and transport it to a beach to replace the sand that has previously been eroded by heavy storms and wave action.

Dredging is used in many other capacities as well. Harvesting materials, for example, is a process by which sediment is dredged for elements like gold, diamonds, or other valuable trace substances. Other examples are: seabed mining, construction materials, anti-eutrophication, contaminant remediation, removing trash and debris from waterways, flood prevention, peat extraction, and oyster harvesting.
