A pattern very similar to AF can be seen in Figure 11, showing very small reductions in interquartile flow, with median change values not exceeding 0.01 ML/day. Percentage changes are close to zero with the 95th percentile not exceeding 2%. The largest percentage change occurs in CLM_006, the most downstream node of Shannon Brook. Due to the comparable small contributing area of this catchment, a reduction of 0.01 ML/day is a relatively large change.
The maximum change in IQR occurs in the second half of the simulation period, with median values close to the end of the simulation period.

The circle indicates the median of the posterior predictive distribution, the length of the thick vertical line spans the interquartile range (or 50th percentile prediction interval), and the thin vertical line spans the 90th percentile prediction interval. Nodes are grouped per catchment, ordered from upstream to downstream.
