Improved calibration scheme of SWAT by separating wet and dry seasons

Abstract: a b s t r a c tSimulation of low flow process is critical to water quality, water supply, and aquatic habitat. However, the poor performance of Soil and Water Assessment Tool (SWAT) in dry seasons has impeded its application to watersheds characterized largely by low-flows. Aiming at overcoming this shortage, a seasonal calibration scheme was proposed, in which SWAT was calibrated separately for the dry and wet periods and the "optimal" simulation results of these two periods were combined into a complete runo… Show more

“…Similar good results were reported when calibrating streamflow under wet and dry seasons separately in [29,30]. Since the NS efficiency metric applies to the whole simulation period, it was not recommended for application to low flow periods of streamflows [27,30].…”

“…Meanwhile, RCHRG_DP played a less important role in the model calibration and ranked from 8 to 14. The parameters defined as sensitive in this study were similar to those selected in other studies with a focus on semi-arid catchments and low flow conditions [2,4,28,30].…”

“…However, there was no advantage when only the winter (wet period) data were used for calibration compared with the conventional calibration method which used the entire data over the whole period. Paik et al (2005), Kim and Lee (2014), Zhang et al (2015) and Kim et al (2016) also used the seasonal calibration method.…”
