Analysis of Groundwater Recharge Changes in the Upper Reaches of the Yangjae Stream due to Changes in Land Material

Year: 2024

Type: article

Abstract: This study analyzes the phenomenon of drought changes in urban areas due to changes in the land components, focusing on Gwacheon City. A SWAT model was constructed, and changes in groundwater recharge and runoff were calculated for drought assessment. The parameters that reflect changes in land components, including the runoff coefficient (Curve Number), soil moisture content (SOL_AWC), soil conductivity (SOL_K), upper roughness coefficient (OV_N), and storage coefficient (CANMX), and affect groundwater recharge, were selected. Changing all five parameters showed that groundwater recharge increased by approximately 3.37% compared with the current level, demonstrating the effect of drought alleviation. Further, when applied to both traffic and residential areas, which are impervious urban areas, the groundwater recharge increased by approximately 10.46%.
