Abstract

The focus of this paper is a comparison of predicted consolidation settlement of sub aqueous capped dredged mounds to changes in mound configuration based on bathymetric surveys. Three capped mounds of contaminated dredged material in the Central Long Island Site have been monitored since 1979. Geotechnical consolidation analyses show that changes in surface elevation can be attributed to consolidation of the cap, contaminated, and base materials rather than to erosion. Pore water migration analyses indicate that the fluid expelled from the consolidated contaminated material is contained within the cap materials.
