This directory includes separate files for the physical catchment properties, land cover data, soil classifications, and hydrological signatures. Each of these files consolidates information related to all 50 catchments.

-------------------------------
HYDROLOGICAL SIGNATURES: 
-------------------------------
These are divided into three separate files, one covering the entire record period (1961-2020), another for the CNP1 (1961-1990), and a third for the CNP2 (1991-2020). It's important to note that the mean streamflow used as reference for computing low- and high-flow frequencies across all three instances was computed from the entire record period (see explanations below).
