(Figure 4). We will assume a 40-percent uncertainty; thus QL-S = 100,000 40,000 m3/year.
These values are then entered into the sediment budget.

Because right-directed transport has been assumed to be constant for the entire barrier, set values
the pre-inlet condition that Q9=Q10=Q11=Q12=0. Use the residual values or the "force
balance cell" option for each cell to determine the unknowns. The final pre-inlet sediment
budget is shown in Figure 5.
