    Hydraulic dredging uses pumps that vacuum excess sediment away. Hydraulic dredging works well when there is adequate area for dewatering and storage of excess sediment. Mechanical dredging uses a dipper to physically scoop excess sediment out of the water. Mechanical dredging is very efficient if the area is accessible by land or by barge
