These need to be removed from time to time. Sometimes there are accidental or deliberate chemical spills.
Waste deposits from factories and residences get accumulated at the bottom of seas and freshwater areas. Many times, new land is created from the ocean, rivers, and lakes by filling it with material collected by dredging.ģ) Environmental Dredging to Keep Waterbodies cleanĭredging is carried out in rivers, lakes ponds and shallow seas. Keeping the depth of waterways at optimum levels is crucial to prevent flooding and also allow passage of ships. Over time, waterways can get choked with sediments and trash if not dredged at regular intervals.
Dredging allows cargo ships of all sizes to dock and not run aground. New waterways are built to improve connectivity with the new trading hubs. What Is Dredging Used For?ĭredge removes sediments, pollutants, and debris, and hence, its applications are manifold. Many times, it is also done to protect coasts, redevelop coast, or to reclaim the land. Special equipment called a Dredge is used to loosen and then suck out the sediment and debris.ĭredging keeps waterways and ports navigable. The material gathered is then deposited to different locations. Dredging refers to the process of excavation of sediments from the bottom or sometimes the banks of rivers, lakes, harbors, and other water bodies.
