Global Distributed Basin Characteristics (GDBC)

About GBDC

9 archived elementary including stream order, stream number, stream length, basin relief, basin length, basin perimeter, maximal flow length, down valley length and overland flow length, and 21 derivable from these elementary morphometric characteristics. Characteristics of basins discharging to every grid-cell of the global earth surface are generated at 1km resolution from the remotely sensed Hydro SHEDS dataset.
