Kling-gupta efficiency kge
WebIncreasingly an alternative metric, the Kling-Gupta Efficiency (KGE), is used instead. When NSE is used, NSE = 0 corresponds to using the mean flow as a benchmark predictor. The same reasoning is applied in various studies that use KGE as a metric: negative KGE values are viewed as bad model performance and only positive values are seen as good ...

WebThe continuous measure adopted is the modified Kling-Gupta efficiency (KGE') [34,35] and its associated components: correlation (r), bias ratio (β), and variability ratio (γ). WebJul 1, 2024 · The spatial biases as well as the temporal variations of the indices were analyzed using the simple bias and the Kling-Gupta Efficiency (KGE) respectively. Subsequently, the best models (models with low biases and KGE close to 1) were used to analyze the trends. The modified Mann-Kendall test showed an increasing trend in the …
WebFeb 1, 2024 · Gupta et al. (2009) showed that optimizing αNSE underestimates the variability of simulated flows because the optimum NSE is attained when αNSE = r. In view of this, Gupta et al. (2009) and Kling et al. (2012) recommended the Kling-Gupta efficiency (KGE) in order to circumvent the connections between the variation coefficient and bias and ratios. WebAug 13, 2024 · ABSTRACT. This study compares single-site, multi-site and multi-variable SWAT calibration. The SWAT model was applied to a large basin (63 884 km 2) and calibrated at a monthly time step with the SUFI-2 algorithm, using the Kling-Gupta efficiency (KGE) as the objective function.Multi-variable calibration was performed by combining …
