The potential alternative uses of dredged material in the Humber Estuary
… alternative uses of the maintenance and capital dredged material which is usually disposed of within the estuary, to alternative suitable locations within the Humber Estuary whilst taking into account the sediment composition and hydrodynamics, as well as the local need, economics and adherence …

A laboratory study of solidification/stabilization technology for contaminated dredged material
Safe disposal of contaminated dredged material has become a significant issue especially as public environmental awareness and concerns increase. Solidification/ stabilization technology potentially may provide for a safer, more effective and more economical means of disposal. This research …

Use of Geographic Information Systems (GIS) to aid in siting dredged material disposal areas
… is hampered by a lack of disposal areas. Current dredged material disposal site selection methodologies have several limitations, such as a lack of early public involvement in the decision making process, inadequate documentation of the assumptions entering into decisions, lack of a holistic view, …

Laboratory Self-Weight Consolidation Testing of Dredged Material Analyzed Using a One-Dimensional Finite Strain Consolidation Method
… the properties which govern the consolidation of dredged material are best determined using a one-dimensional finite strain consolidation theory. This method requires a complete relationship between void ratio and effective stress for all expected void ratios in a dredged layer, which can be …

GEOTECHNICAL CHARACTERIZATION OF BALTIMORE DREDGED SEDIMENTS AS AN INFILTRATION BERM MATERIAL ON HIGHWAY SLOPES
Baltimore Harbor dredged material has limited use in common geotechnical construction due to its soil composition. It has low shear strength for foundation applications and lack of plasticity makes it an undesirable material for seepage barrier applications. Vegetated infiltration berms, used for …

An evaluation of the standard elutriate test as an estimator of contaminant release at the point of dredging
While release of contaminants during dredged material disposal operations has long been the subject of environmental concern, the potential release of pollutants during the dredging process has recently come under the scrunity of federal and state regulatory agencies. The mechanical action of a …

Modeling of the fate of lead due to the removal of corroded sub-marine cables in aquatic environments
… which lead is released from corroded cables and dredged material are complex, but have to be taken into consideration when assessing the potential risk of dredging and removal activities. In this research, the effect of various physical factors on the release and dispersion of lead from corroded …

Vegetative Community and Health Assessment of a Constructed Juncus-Dominated Salt Marsh in The Northern Gulf Of Mexico
… as sites for restoration using beneficial use dredged material, and two sites of differing age have since been planted with <em>Spartina alterniflora, Juncus roemerianus, Uniola paniculata, S. patens, </em>and <em>Panicum amarum</em>. Ecological assessment and monitoring of this restoration …

Nanoscale geochemistry of critical elements; applications for mineral exploration and recovery from secondary sources
… two secondary sources; acid mine drainage, and dredged material. Continued study of critical element nanogeochemistry, and development of spICP-MS can further efforts to explore for both conventional and unconventional resources.

Dynamics of particle clouds in ambient currents with application to open-water sediment disposal
… purchased sediment, in the former example, and dredged material (both clean and contaminated), in the latter example. This shows the significant economic and environmental interests in the accurate placement of sediment, which requires knowledge of how particle clouds behave in ambient currents. …

Beneficial Reuse of Dredged Materials in Upland Environments
… excavated from dredging operations are known as dredged materials. Beneficial reuse of dredged materials in confined utilization facilities (CUFs) is a new approach that has the potential to productively utilize large quantities of dredged materials. However, several factors can inhibit the use …

Nearshore sediment dynamics in a mixed sand/mud environment
… the suitability of capital and maintenance dredged material for use in reclamation, have been evaluated. Within the study site, near-bed wave orbital velocities and fluvial inputs control the spatial variability in the seabed sediment textural characteristics, with the seabed grain size …

Sandbars managed for least terns within the Missouri River: evaluating the influence of fish, spatial scale and environment on habitat use
… of breeding habitats, including placement of dredged material specifically as nesting substrate. Wide expanses of barren land are known to attract Least Terns, yet specific small scale habitat features are thought to trigger nest habitat selection. Yet as a plunge-diving piscivore, Least Terns …
