Possible reasons for dredging include improving existing water features reshaping land and water features to alter drainage, navigability, and commercial use constructing dams, dikes, and other controls for streams and shorelines and recovering valuable mineral deposits or marine life having commercial value. Impacts on ecology: Dredging can damage ecology by directly affecting its physical habitat, disrupting riverine processes and reduced connectivity with the floodplain.
