...Several graphical techniques are also described briefly because graphical techniques provide a visual comparison of simulated and measured constituent data and a first overview of model performance (ASCE, 1993) and are essential to appropriate model evaluation (Legates and McCabe, 1999)....

...Although r and R2 have been widely used for model evaluation, these statistics are oversensitive to high extreme values (outliers) and insensitive to additive and proportional differences between model predictions and measured data (Legates and McCabe, 1999)....

...The index of agreement can detect additive and proportional differences in the observed and simulated means and variances; however, d is overly sensitive to extreme values due to the squared differences (Legates and McCabe, 1999)....

...A number of publications have addressed model evaluation statistics (Willmott, 1981; ASCE, 1993; Legates and McCabe, 1999), but they do not include recently developed statistics (e....

...…of model skill, there has been a long and vivid discussion about the suitability of NSE (McCuen and Snyder, 1975; Martinec and Rango, 1989; Legates and McCabe, 1999; Krause et al., 2005; McCuen et al., 2006; Schaefli and Gupta, 2007; Jain and Sudheer, 2008) and several authors have…...

...For such situations, various authors have recommended the use of the seasonal or climatological mean as a baseline model (Garrick et al., 1978; Murphy, 1988; Martinec and Rango, 1989; Legates and McCabe, 1999; Schaefli and Gupta, 2007)....

...…or reporting results based on calibration with NSE, information about the correlation, bias, and variability of flows should also be given (interestingly, this was already proposed by Legates and McCabe (1999), although they did not discuss the interrelation between NSE and its three components)....
