Evaluation of Loading and Dredged Material Overflow from Mechanically FilledHopper Barges in Mobile Bay, Alabama

摘要

Large mechanical dredges with clamshell buckets are being used for the new-workdredging. Hopper barges arae loaded with the dredged material and transported by tug to the disposal site. Mechanical dredging is also the most likely technique for future maintenance. The economic loading of the hopper barges and the potential environmental impat associated with barge overflow during loading are important issues.
