The Glob­al Stream­flow Char­ac­ter­is­tics Dataset (GSCD) con­sists of glob­al maps of 17 stream­flow char­ac­ter­is­tics, such as base­flow index, runoff coef­fi­cient, and flow per­centiles, pro­vid­ing infor­ma­tion about runoff behav­ior for the entire land sur­face includ­ing ungauged regions. The maps are unique in that they were derived using a data-dri­ven (top down) approach based on stream­flow obser­va­tions from thou­sands of catch­ments around the globe, rather than using a phys­i­cal­ly-based (bot­tom up) process mod­el. For more infor­ma­tion, see the fol­low­ing open-access papers:

Maps of estimated and observed baseflow index (BFI).

Esti­mat­ed (top) and observed (bot­tom) val­ues of the base­flow index (BFI), one of the 17 stream­flow char­ac­ter­is­tics includ­ed in the GSCD.

Acknowl­edge­ments

P17-JRC_referenceThe GSCD was devel­oped by Hylke Beck (Prince­ton Uni­ver­si­ty, Prince­ton, USA) in col­lab­o­ra­tion with Albert van Dijk (ANU, Can­ber­ra, Aus­tralia), Ad de Roo (JRC, Ispra, Italy), Diego Miralles (VU Ams­ter­dam, The Nether­lands), Jaap Schellekens (Deltares, Delft, The Nether­lands), Tim McVicar (CSIRO, Can­ber­ra, Aus­tralia), Richard de Jeu (Trans­mis­siv­i­ty, Noord­wijk, The Nether­lands), and Sam­purno Brui­jnzeel (King’s Col­lege Lon­don, UK). The Glob­al Runoff Data Cen­tre (GRDC) and the US Geo­log­i­cal Sur­vey (USGS) are thanked for pro­vid­ing most of the flow data.
