Parameter Sensitivity Analysis of SWAT Modeling in the Upper Heihe River Basin Using Four Typical Approaches

Abstract: Parameter sensitivity analysis is a significant part of quantifying model uncertainty, effectively identifying key parameters, and improving the efficiency of parameter optimization. The Soil and Water Assessment Tool (SWAT) model was applied to the upper Heihe River basin (UHRB) in China to simulate the monthly runoff for 11 years (1990–2000). Four typical sensitivity analyses, namely, the Morris screening, Sobol analysis, Fourier amplitude sensitivity test (FAST), and extended Fourier amplitude sensitivity t… Show more

“…The parameters identified through the sensitivity analysis closely resemble those found in other studies using hydrological modeling with the SWAT model (e.g. Lenhart, 2002;Tang et al 2012, Premanand et al 2018Taleb et al 2019;Xiang et al 2022).…”

“…Originally designed to predict water quantity and quality at the watershed level under various meteorological and spatial conditions and at different time scales (daily, monthly and yearly), SWAT can also aid in planning and decisionmaking processes aimed at environment protection and ensuring water availability for future uses (Silva et al 2015;Fatichi et al 2016). SWAT has been utilized in numerous projects worldwide (Sophocleous and Perkins, 2000;Tripathi et al 2003;Hao, 2004;Laurent, 2007;Xiang et al 2022), and has been applied in several watersheds in Algeria (Zettam et al 2017;Hallouz, 2018;Otmane et al 2019;Mami et al 2021).…”
