Nash and sutcliffe 1970

WitrynaTraditionally, the Nash–Sutcliffe efficiency (NSE, Nash and Sutcliffe, 1970) is an often-used metric, in part because it normalizes model performance into an interpretable scale (Eq. 1): where T is the total number of time steps, Qsim(t) the simulated discharge at time t, Qobs(t) the observed discharge at time t, and the mean observed discharge. Witryna29 kwi 2016 · To evaluate the hydrological model performance, the coefficient of determination (R 2) and Nash-Sutcliffe Efficiency (NSE) (Nash and Sutcliffe 1970) were calculated. Comparison between the observed and simulated values gave R 2 = 0.8 and NSE = 0.78. The calibrated result of the daily flow of the Prek Te is shown in Fig. 5.
