Abstract

This study assessed the impact of increased groundwater use on watershed hydrology in Han River basin (35,770.4 km2) by applying groundwater use data from the 1980s (1976-1985) and 2010s (2006-2015) to SWAT (Soil and Water Assessment Tool). The groundwater use data was established using groundwater survey yearbooks and applied to each subbasin using WUS tool of SWAT. SWAT was calibrated at 4 multi-purpose dams and 3 multi-functional weirs under 2010s weather and groundwater use conditions. The average calibration results at 4 dams and 3 weirs showed that 0.76 of R2, 0.68 of NSE, and 2.13 mm/day of RMSE, respectively. After, 1980s groundwater use data was applied to the calibrated SWAT under the same weather conditions. The impact of increased groundwater use revealed a decrease in the average streamflow from 58.0 m3/sec to 55.1 m3/sec, representing an approximate 5.29% reduction. The total runoff (TR), baseflow (BF), and groundwater recharge (GWR) decreased by 2.5%, 20.6%, and 20.7%, respectively. Seasonal analysis indicated that TR notably decreased during autumn and winter, while BF showed a maximum reduction of 25.6% during summer season.
