Regardless of the important interest in global hydrological modeling, few systematic evaluations of worldwide hydrological models (gHMs) at the catchment scale have already been carried out. This study investigates the overall performance of four gHMs driven by 4 international observation-based meteorological inputs at simulating weekly discharges more than 198 large-sized North American catchments for the 1971010 period. The 16 discharge simulations serve because the basis for evaluating gHM accuracy at the catchment scale inside the second phase from the Inter-Sectoral Effect Model Intercomparison Project (ISIMIP2a). The simulated discharges by the four gHMs are compared against observed and simulated weekly discharge values by two regional hydrological models (rHMs) driven by a global meteorological dataset for the same period. We discuss the implications of each modeling approaches at the same time as the influence of catchment characteristics and global meteorological forcing with regards to model efficiency through statistical criteria and visual hydrograph comparison for catchment-scale hydrological studies. All round, the gHM discharge statistics exhibit poor agreement with observations in the catchment scale and manifest considerable bias and errors in seasonal flow simulations. We confirm that the gHM method, as experimentally implemented by means of the ISIMIP2a, should be made use of with caution for regional research. We obtain the rHM strategy to become far more trustworthy and advocate applying it for hydrological studies, specially if findings are intended to help operational decision-making.
