Beach nourishment—beach restoration in which hydraulically pumped dredge material is directly placed onto an eroded beach.
Confined—placement of dredged material within diked nearshore or upland confined placement facilities that enclose and isolate the dredged material from adjacent waters.
Underwater confined—placement of dredged materials in an underwater area that is capped or otherwise isolated from the surrouding area.
Mixed—dredging operation that uses more than one dredged material placement alternative.
Overboard—placement of dredged material in rivers, lakes, estuaries, or oceans via pipeline or surface release from hopper dredges.
Open water/upland—combination of open water and upland placement of dredged material.
Upland/beach nourishment—combination of upland placement and beach nourishment using dredged material.
Upland—placement of dredge material on land above adjacent water surface elevation.
Wetlands nourishment—wetland restoration in which hydraulically pumped dredge material is directly placed in a wetland area.
Undefined—undefined or unknown at the time of data entry.",,,,,,,,,,
