Figure 25: The predicted worst case mean depositional thickness at dump site #2 over the duration of the simulation period for the Cutter Suction dredger. Copied from Figure B.2.9 in Van Ballegooyen et al., 2006) 75
Figure 25 depicts the simulation model predictions of the 'worst case' average deposition thickness for site #2. Similar to site #1 the bulk of the discharged sediment is contained within the designated dump area. However, there is an extensive area where deposition occurs, albeit in shallow layers (
