River width is a fundamental parameter of river hydrodynamic simulations, but to date no global-scale river width database based on observed water bodies has been available. Here we present a new algorithm that automatically calculates river width from satellite-based water masks and flow direction maps. The Global Width Database for Large Rivers (GWD-LR) is developed by applying the algorithm to the SRTM Water Body Database and the HydroSHEDS flow direction map.
