Dredging is an excavation operation that is generally done at least partially underwater in shallow water locations to collect bottom sediments and dispose of them at a new site. It is a method of moving natural resources from one section of the sea environment to another using specialized dredging vessels. Dredging's major goal is to maintain rivers and ports passable, as well as to build new ports, coastal protection, land reclamation, and the extraction of sediments such as sand and gravel for use in the building industry.
