To reduce the exposure of fish, wildlife, and people to contaminants in the water and avoid further spread of the contaminants in the water bodies, the dredging activity very significant. The pollution of water bodies from the influx of contaminated sediments that come in from cities and industrial sites has necessitated the need for dredging. The various sources that cause pollution include seawater overflows, municipal and industrial discharges, and spills. Damages caused by adverse weather conditions and increased climatic changes are righted through dredging. Reclamation is needed as a result of rising sea levels and storm damages which have affected many cities. Port maintenance is made effective by the use of dredges.
