Short summary

This study shows that multisite calibration approaches for a distributed hydrologic model far exceed a calibration based on only the basin outlet. It also reveals advantages of semi-distributed over (non-parsimonious) fully distributed parameter schematization, by means of improved predictive capacity and reduced parameter uncertainty. The uncertainty in future streamflow resulting from variations in projected climate between GCMs substantially outweighs the calibration uncertainty.
