Figure S1. Correlation matrix of the Baseflow index (BFI),
defined as the ration of baseflow to total streamflow
(\(\frac{Q_{B}}{Q}\)), of the 731 Brazilian’s catchments evaluated in
this study. We computed BFI according to 5 different streamflow
partitioning methods: Lyne and Hollick filter (one and three passes),
Eckhard filter and United Kingdom Institute of Hydrology smoothed minima
method – 5 (UKIH5) and 90 (UKIH90) days.
