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.

Witryna3 sie 2024 · Based on Nash and Sutcliffe (1970), the value of NSE indicates that how well the predicted values and actual values fit the 1:1 line, the values ranged from infinite to one. The lower or closer values to zero indicating poor model performance, whereas, if the value is equals to one shows perfect model performance. Witryna2.1.

Witryna1 sie 2024 · Nash-Sutcliffe efficiency coefficient (NSE) – This normalized indicator of model efficiency corresponds to the statistical agreement or skill of the estimates … Witryna2.1. Nash-Sutcliffe Efficiency The NSE suggested by Nash and Sutcliffe (1970) is expressed as one minus the mean of the squared errors between the observed and simulated datasets normalized by the variance of the observed values during the validation period, which is the most widely attention goodness-of-fit indicator in the model Nash–Sutcliffe efficiency can be used to quantitatively describe the accuracy of model outputs other than discharge. This indicator can be used to describe the predictive accuracy of other models as long as there is observed data to compare the model results to.
