2.6.1.6.8 Longest low-flow spell (LLFS)

The medians of absolute maximum change in Figure 17 indicate that the LLFS across the region is to increase by up to 8 days. As for the changes in LFS and LFD, this occurs at the downstream nodes of Shannon Brook.

Figure 17 Predictive distribution of (a) maximum raw change (amax), (b) maximum percent change (pmax) and (c) year of maximum change (tmax) for the number of longest low-flow spells (LLFS)

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.
