Global River BankFull Discharge (GQBF) - Siberia(SI) & South Pacific/Australia(SP)

The GQBF is the estimated bankfull discharge across ~2.87 million km (length) of global river reaches. The bankfull discharge here is defined as the maximum flow rate contained within a river just before inundation occurs in the surrounding floodplain. We based our river bankfull discharge estimation on a newly developed river network, Global RIver Topology (GRIT), using GRIT’s river reaches as the spatial scale to represent the variation in bankfull discharge. We included all GRIT river reaches that coincided with the Global River Width from Landsat (GRWL) river masks (with overlapping ratio >=0.5). This selects river reaches with satellite-derived width measurements >=30 m, resulting in a total length of ~2.87 million km. Here, the GQBF represents the time-averaged bankfull discharge at <1 km (river length) spatial resolution.

The subcontinental catchment groups (vector, polygons) can be found at GRIT domain polygon (GRITv06_domain_GLOBAL.gpkg.zip). They allow for more fine-grained subsetting of data .

Vector files are provided in geographic WGS84 coordinates (EPSG:4326).
