| Abstract |
This study analyzed changes in groundwater recharge due to urbanization and future climate change using the SWAT hydrological model in the Anseong river basin (1,647 km2) adjacent to the west sea of Korea. The urbanization scenario was constructed based on increasing urban density and expansion, resulting in a decrease in groundwater recharge and recharge rate by 19.9 mm and 1.77 %, respectively. Future climate change scenarios were simulated using two models representing extreme rainfall and drought, with the drought model indicating that maintaining an average recharge rate of 21.6 % would be challenging. Results from the combined scenario of urbanization and extreme drought suggest that groundwater recharge during the spring season in urban areas would be most significantly affected. |
