Accuracy comparison of applying the POT and BM methods using different parameters for Watari basin. Model 1–6 indicate the precipitation data come from current scenario and the parameter corresponds to the value of Model 1–6 in Table 1. Blue points and lines represent the basin AMFS and frequency curve, respectively. Red points and lines indicate the regional AMFS and frequency curve, respectively. Green dashed lines show the BIAS between the basin and regional results
