A quick guide: What is Dredging?
Dredging is the excavation of material from the bottom of waterways to deepen or clean them or from the ocean to use for beach restoration or reclamation.
This includes both the excavation and removal of a variety of materials – sediment, sand, rock and debris – from waterways, such as harbours, ports, lakes and rivers, usually for the purpose of deepening or cleaning them. Sand excavated from the ocean is used for beach restoration and land reclamation.

Dredging deepens ports and access channels to accommodate global waterborne freight transport of goods. Dredging also excavates or ‘mines’ sand from far offshore and then transports these materials to onshore locations where they are used to replenish eroded beaches and rebuild coastlines for protection of low-lying areas. Modern dredging vessels and technologies can collect and transport large quantities of sand to improve and expand existing ports, and to build land reclamations, which form platforms for offshore airports, residential and commercial areas.
