This Coastal and Hydraulics Engineering Technical Note (CHETN) documents geotechnical research performed by the U.S. Army Engineer Research and Development Center (ERDC) specifically for the Boston Harbor Navigation Improvement Project. Laboratory modeling of the subaqueous sand capping process was conducted to allow a comparison to field performance of sand capping dredged material in a confined aquatic disposal cell. The practice of covering subaqueous contaminated disposed dredged material with a clean isolating material has been conducted since the 1970s, and is a cost-effective alternative to other disposal options (Palermo et al. 1998). Capping has been especially suitable for isolating disposed contaminated dredged material in confined aquatic cells such as pre-existing subaqueous pits where the dredged material is laterally confined. An isolating cap typically composed of clean sand is superimposed on the top of the previously placed dredged material in such a fashion as to encapsulate the exposed surface of the dredged material (Figure 1).
