Examining thin layer cap behaviour in a freshwater industrial harbour

PurposeA sediment remediation project in Hamilton Harbour, Lake Ontario, Canada, proposes to use a thin layer cap for managing residual contamination from dredging as well as areas of marginal contamination not included in the dredge plan. Bottom shear stress (BSS) from weather, as well as propeller wash, have the potential to severely erode thin layer caps. The proposed thin layer cap was examined with respect to the BSS expected in Hamilton …
