Dredging is the removal of sediment and debris from the bottom of lakes, rivers, harbors and other bodies of water. It’s a daily necessity on waterways around the world as sediment – the natural process of sand and silt washed downstream – gradually fills canals and harbors.
Dredging often aims to maintain or increase the depth of shipping channels, anchorages, or mooring areas to allow the safe passage of boats and ships.
River dredging is necessary to maintain natural river flows and appropriate water depths to minimize the risk of potential disasters.
