Harbor maintenance involves the regular upkeep and repair of ports and harbors to ensure safe and efficient operations. This includes dredging to remove sediment, repairing docks and piers, and maintaining navigational aids like buoys and lights. Proper maintenance helps prevent accidents and supports the economic activities that rely on maritime transport. Additionally, harbor maintenance is essential for protecting the environment. It helps manage water quality and supports local ecosystems by preventing erosion and sediment buildup. Agencies like the U.S. Army Corps of Engineers often oversee these activities, ensuring that harbors remain functional and environmentally sustainable.
