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.
