Why is hydraulic dredging not the sediment removal method?
Hydraulic dredging for the removal of the sediment was considered and deemed unfeasible in the case. The method is not feasible due to the shallow depth of water at the site and small volume of sediment to be dredged. In addition, for this project the cost of hydraulic dredging is greater than the cost of mechanical dredging. Dredging techniques is not one of the demonstration goals identified for this project. Studies on the type dredging techniques would be better suited for a larger project area without depth and access constraints.
