Abstract Global 1-degree data sets provided within the framework of the Second Global Wetness Project (GSWP-2) were applied for the simulation of river flow from 12 MOPEX (Model Parameter Estimation Experiment) experimental river basins (with an area of the order of 103 km2) to reveal the applicability of global forcing data and land surface parameters for regional runoff predictions. The simulations were performed at 3-h time steps for a 10-year period (1986–1995) using the SWAP land surface model (Soil Water–Atmosphere–Plants). The results of simulations were compared with the observed streamflow and with analogous simulations based on the regional data set. The comparison allowed us to reveal the influence of uncertainties in the forcing data and the land surface parameters on runoff prediction.
