Modeling the hydrochemical drain of the mountain rivers. 2. Assessment the quality of models of mineral nitrogen drain

Quality of mathematical models of drain the various mineral compounds of nitrogen (NO2-, NO3-, NH4+) on the example of 34 rivers of Altai-Sayan highland is estimated. Sensitivity of models to natural variations of factors of the environment is defined. The full component analysis of their discrepancy dispersion is carried out. The calculated Nash-Sutcliffe's coefficient of NSE=0,66 answers the high quality of models that it allows to count seasonal and long-term dynamics of hydrochemical drain for various rivers of Altai-Sayan highland, including at limited hydrometeorological and hydrochemical information on river basins.
