Comparison of potential groundwater recharge in the rainy season of 2017 and 2018 by modeling with soil moisture in the Haean basin, Yanggu

초록

In this study, we have simulated the potential groundwater recharge using soil moisture and meteorological data. The data have been collected every 10 minutes for 586 days in the Haean basin of Yanggu, Gangwon. The soil moisture content was higher at deeper depths, lower slopes and many rainfalls. Soil moisture contents in the field and simulation are related to high correlation as 0.9 to 0.93. The potential groundwater recharge for rainy season data has been estimated using HYDRUS-1D. The potential groundwater recharge of YHS2 was 555 mm in 2017, 332 mm in 2018, and the YHS3 was 418 mm in 2017, 408 mm in 2018.
