Abstract: Highlights Five calibration schemes were conducted for the SWAT model, utilizing different combinations of streamflow (SF), remote sensing soil moisture (RS-SM), and remote sensing evapotranspiration (RS-ET). A Repeated Measures Design was applied for performance evaluation, assessing stability measures at the sub-basin scale for each calibration scheme. Calibration schemes incorporating RS-SM and RS-ET, along with streamflow, exhibited greater stability compared to schemes using streamflow alone. SF + ET + SM and SF + ET calibration schemes demonstrate more stability in ET simulation. SF + ET + SM and SF + SM calibration schemes exhibit more stability in surface runoff and SM simulation.
