Figure 8.19. Absolute normalised error (ANE) of predicting low flows in ungauged basins as a function of aridity (E
PA
/P
A
), mean annual
air temperature (T

), mean elevation and catchment area for different parameter regionalisation methods. Lines connect median efficiencies for
the same study. Boxes are 40%

60% quantiles, whiskers are 20%
