Phosphate and thermal stabilization of heavy metals in dredged sediments
Treatment and reuse of dredged harbor sediments in construction as an alternative to disposal reduces costs and conserves resources. This research focused on leachability of metal contaminants subsequent to phosphate addition and thermal treatment at 700 C. X- ray absorption spectroscopy (XAS) in …

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 …

Finite element modeling of contaminant transport through confined disposal facilities
… channels which produces about 300 million yd³ of dredged sediments annually. Many of these sediments have to be contained within confined disposal facilities (CDFs) due to the presence of heavy metals, PCB’s and other harmful constituents within the pore water of the dredge soils. However, these …

Physical and geochemical characterisation of canal sediments in the Black Country, West Midlands.
… sediment matrix and processes occurring in the sediments. Dredging of canals is needed for navigability purposes and consequently testing of dredged sediments (to assess whether sediments are hazardous) and landfilling can be costly for British Waterways facing constantly changing regulations …

Coastal and sediment dynamics in a high-energy, rocky environment
… and iv) experimental dumping of 47,000 m³ of dredged sand in a rocky nearshore zone (6-10 m depth). Sediment trap calibration experiments were also performed. Analysis of the measured wave data has identified wave-induced motion as a significant source of velocity error in p, u, v meters on …

Nearshore and inner shelf sedimentation on the east Coromandel coast, New Zealand
… provide information on the mobility of surface sediments under different sea conditions; the collection, of 174 km of continuous sub-bottom seismic profiles which have been used to determine sub-surface stratigraphic patterns; and an examination of the provenance of shelf sediments through a …
