Dredging Operations Technical Support Program. Methodology for Analysis of Subaqueous Sediment Mounds
Abstract
Dredging of contaminated sediments and subsequent disposal and capping in legally designated sites is an internationally accepted disposal alternative when adherence to strict disposal practices is maintained. As more highly contaminated sediments in the heavily industrialized harbors of the world must be dredged to maintain navigation and economic viability, pressure to use subaqueous dredged material disposal sites will increase. Use of these subaqueous sites has necessitated development of procedures to analyze disposal site capacity based upon physical, chemical, and biological considerations. This study developed an analysis method to investigate the behavior of the created subaqueous sediment mounds. Emphasis was placed upon the physical aspects of mound behavior, although the method also includes chemical and biological aspects. The physical aspects of the method were applied to four field sites at which dredged material mounds have been created. The procedure successfully predicted the physical behavior of the constructed dredged material mounds. This method of analysis provides a useful tool for evaluation of subaqueous disposal sites and the dredged material mounds created within these sites; it is equally applicable to analysis of contaminated and uncontaminated dredged material mounds. Keywords: Underwater dredged materials; Waste disposal consolidation; Site capacity; Soft soils.
