the present practice of assessing the performance of the hydrological model based on just the streamflow needs to refined in such a way that the performance index used will tell us about the all the different processes at work. Therefore, calibrating or measuring the performance of the hydrological model on the basis of the streamflow observation will not guarantee a complete calibration of the model in mimicking the underlying hydrologic system. Therefore, it is necessary to have mutliscale performance analysis of a hydrologic model in order to capture the features at all scales.Â
Recently, Rathinasamy et al.,(2014) have proposed the wavelet based multiscale measure for hydrological model performance analysis. It was shown that these measures are superior in assessing the model performance in comparison with the other measures. And the multiscale measures can be used as reliable measure for evaluating the model's ability in capturing the multiscale features of the underlying system. It is to be noted that the above study only considers the discharge for performance analysis and uses a multiscale Nash Sutcliffe criteria as an underlying basis.
