Abstract: Evaluation of suspended material migration was a task in a study of sediment-associated contaminant migration. New Bedford Harbor is a vertically well-mixed, shallow estuary with little vertical circulation, and generally low current velocities. Suspended material generally migrates from Buzzards Bay upstream in the estuary at concentrations generally below 10 ppm, and settle in the upper harbor at about 2,200 kg per tidal cycle. Tidal pumping was the dominant transport component for suspended material, and usually varied vertically. Mechanisms involved in upstream transport depended on tidal variations in vertical mixing.
