How much dredged material is moved annually?
You can quantify dredging around the world in financial terms such as turn over (est. global turnover in 2008 €10.225 mlio.) Dredging in Figures. However, the total amount of m3 dredged annually has not yet been estimated. It makes little sense to do so since a cu.m. of silt is not the same as a cu.m. of rock being dredged. The total amount of dredged material annually depends heavily on the specific projects being executed during a specific year.
