Programs that are responsible for discharging, depositing, dumping or otherwise disposing of sediment produced by dredging operations. Options generally include placing the materials in ocean dredged materials disposal sites, on a beach (usually to replenish an eroding beach or protect an eroding wetland), behind dikes which contain and isolate it from the surrounding environment, and in flow-lanes and behind bank placements in high-energy river systems with rapidly flowing water and strong currents. In situations where dredged materials are badly contaminated, capped in-water disposal is used. The contaminated dredged material is placed on a level bottom or in deep pits or bottom depressions. Clean material, usually sand, is dropped on top. Caps are designed so that currents, waves, or the burrowing bottom creatures will not erode the protective layer over time and are continually monitored for signs of failure.
