Dredging is a process that involves excavating or removing sediment and debris from the bottom of bodies of water. This is typically done using a dredge, a machine designed for this purpose. The primary goals of dredging include maintaining navigable waterways for shipping and recreation, increasing the depth of harbors and canals, and obtaining materials for construction or land reclamation.

There are several types of dredging methods. Mechanical dredging utilizes equipment like clamshell buckets or backhoes to lift material from the seabed. Hydraulic dredging, on the other hand, uses suction to remove sediment and water, often transporting it through pipes to a disposal site. Specialized dredges are employed depending on the nature of the material to be removed and the specific requirements of the project.

The dredged material, known as spoil, can be disposed of in various ways. It may be dumped at sea, deposited on land in designated areas, or sometimes beneficially reused for purposes such as creating wetlands or filling depleted quarries. Dredging operations can have environmental impacts, and regulatory bodies often oversee these projects to mitigate potential harm to aquatic ecosystems, water quality, and marine life. Environmental assessments are commonly required before dredging can commence.
