Abstract

Self-weight consolidation of a capped dredge disposal mound in Central Long Island Sound is compared to periodic bathymetric surveys. The properties of the dredged materials and the seabed were determined from a geotechnical characterization program conducted on samples obtained at various stages during mound construction and beyond. Predictions from two modeling approaches are in good overall agreement with the bathymetry. This finding agrees with other monitoring studies that suggest that little or no erosion has taken place and that all the deposited sediments are well contained in their present state. Calculations indicate that nearly three years after construction of the mound well over 90% of primary consolidation has been completed.
