Table 1. Model Performance for Gauged Catchments and Ungauged Catchments (Kriging Regionalization) by Cross-Validation, Both for the Calibration and the Verification Periods. ME: Median Nash–Sutcliffe Efficiency of Runoff Plus or Minus Difference of 75% and 25% Quantiles of Efficiencies, that is, a Measure of Scatter. Bias: Median Relative Volume Errors of Runoff Plus or Minus Difference of 75% and 25% Quantiles of Relative Volume Errors. Statistics are for 308 Catchments in Austria. (
