Abstract |
Nitrate contamination primarily results from agricultural activities and wastewater inputs, potentially leading to groundwater pollution. This study analyzed the reactive transport of nitrate in surface-groundwater interactions in the Gadeok-myeon, Cheongwon-gun, using integrated SWAT, MODFLOW, and RT3D models. The study used SWAT to simulate hydrological cycles, MODFLOW for groundwater flow analysis, and RT3D to model the reactive transport of nitrate. SWAT was used to estimate daily groundwater recharge and nitrate concentrations, which were then input into MODFLOW and RT3D models. The results showed that groundwater flow and reactive transport of nitrate were effectively simulated, providing insights into improving predictive models for groundwater and surface water interactions. |
