Summary: Knowing the spillage/efficiency of your cutter dredge, when dredging sand or gravel, could save considerable amounts of money on an operation, and this paper will show the best way to determine it.

• A new analytical model has been developed for the spillage of a cutter head
• Based on physics, new scale laws have been derived for spillage
• The model has been calibrated with the den Burger (2003) experiments
• The model is validated with the Miltenburg (1983) experiments
• The model (Excel) can be downloaded on ResearchGate/Miedema
