Year: 1992-1993

.

Project Description: Mississippi Sound channel improvements required removal of 1 MCY from the channel (maintenance material) that were subsequently placed in a thin layer with thickness = 12 in. in three, 300-acre disposal areas along the west side of the channel. Similarly, 1 MCY of new work material was removed and placed in a thin layer with thickness = 12 in. in three, 300-acre disposal areas along the east side of the channel. The material was placed with a spreader barge in each disposal area during three separate disposal events. Each disposal area was monitored for water quality and benthic community responses predisposal, during disposal, short-term postdisposal, and long-term after post disposal.
