Description: Technical note
PURPOSE: Sediment resuspension and loading characteristics of a Conventional (open-faced) clamshell bucket, an Enclosed clamshell bucket, and a CableArm® clamshell bucket were studied under similar operating and environmental conditions in Boston Harbor during August 1999. Monitoring was conducted to characterize each buckets near and far field sediment resuspension characteristics. Bucket-loading characteristics were investigated with regard to water-to-solids ratios dredged by the different buckets. Documentation of sediment resuspension in the water column and loading characteristics with conventional and enclosed clamshell buckets (a bucket type that includes both the contractor-built Enclosed and the CableArm buckets) will assist U.S. Army Corps of Engineers (USACE) Districts in making bucket selection decisions and provide data for the fate of dredged material numerical model verification.
