Introduction: Areas acceptable for the disposal of dredged material are becoming scarce, particularly for projects surrounded by wetlands or open water. To help alleviate this situation, several US Army Corps of Engineers (USACE) Districts have noted that by proposing to place dredged material in relatively thin, uniform layers (the exact thickness depends on the project), additional disposal sites can often be obtained. These sites become available because thin-layer disposal potentially reduces impacts to biota, making disposal in certain areas environmentally acceptable, or because thin-layer disposal can make an upland site more useable for certain aetivities after dredging has ceased, making disposal easements more attractive to landowners. The independent development of the concept of thin-layer disposal by different Corps Districts for use in different habitats has resulted in some confusing and partly contradictory terminology. Headquarters, US Army Corps of Engineers, via the Dredging Operations Technical Support program (DOTS), has asked the US Army Engineer Waterways Experiment Station to examine thin-layer disposal in its multiple forms as applied by the various Districts. A first step in this process is developing a more consistent terminology.
