Overview:

Stream network properties were calculated using TopoToolbox V2 (Schwanghart & Scherler, 2014).

A nationwide digital elevation model (DEM) acquired in 2013 and generated through airborne Interferometric Synthetic Aperture Radar (IfSAR) was used for the analysis (Grafil and Castro, 2014).



Stream network properties:

Attributes for area [km2] (area_km2), elevation [m] (elev_m), stream slope [m/m] (slope_m_m), stream order [-] (streamord) and distance to outlet [km] (distout_km) are averaged over 1 km segment lengths.
