2.6.1.6.3 Daily streamflow at the 99th percentile (P99)

Figure 12 shows a small decrease in the P99 at all 16 model nodes. The 95th percentile of change in P99 does not exceed 0.35 ML/day. The median values of percentage change are all less than 0.001%. The median year of maximum change in the catchments with non-zero median absolute changes is close to 2050.

Figure 12 Predictive distribution of (a) maximum raw change (amax), (b) maximum percent change (pmax) and (c) year of maximum change (tmax) for daily streamflow at the 99th percentile (P99)

d/s = downstream of; u/s = upstream of

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.
