Losses of fill can occur for several reasons and can result in not meeting the quantity of fill required for the dredging operation.
When assessing the quantity of dredged material needed for a reclamation site, the amount of material potentially lost must be considered.
How material is lost
Material can be lost if the dredger is not able to extract all the material and leaves behind a certain volume of spill. These losses may occur because of:
- the currents in the borrow area;
- the overflow from the trailing suction dredgers or barges; or
- discharge through the weir boxes.
If too much material is lost, the balance between the fill required and the quantity available will be adversely affected and remedies must be considered.
