Wet Dredging

Please help improve this article by expanding it. |
Wet dredging is a dredging process done with out removing the water from a Canal segment. This process is performed with a dredge boat and an attached hydraulic shovel. The boat simply drives to the location of sediment build up in the Canal and the hydraulic shovel removes the silt and discharges it to a sealed container on the boat. The collected silt is then disposed of.
The benefit of wet dredging is it can remove large amounts of localized sediment quickly with out removing the water in the Canal. A disadvantage is the inability to quantify whether enough of the contracted sediment was removed.[1] Also, this method of dredging is only able to remove sediment from the central area of a Canal in order to avoid damage to the Canal Wall.[2]
