“…The sedimentary rocks and granites are distributed in the southern and northern part of the study regions (Won and Lee, 1992;Kwon, 2001). According to the Unified Soil Classification System (USCS), the soil in the study area is mainly sandy and contains clay and silt and it is classified into well-graded sand (SW, SW-SM and SW-SC), but some soil layers classified as poorly-graded sands (SP-SM and SP-SC) (Kim et al, 2020). Based on the pumping tests performed on the groundwater well (300 m depth) of Mt.…”

“…By comparing the continuous longterm measurement of soil moisture and temperature by in-situ sensors with meteorological data (e.g., precipitation and air temperature), the increase in soil moisture by precipitation and melting of frozen ices in the soils was determined (Seo et al, 2020). Moreover, a year-round measurement using the 5TM (Decaton, United States) sensors was effectively performed to study the thermal diffusivity and active layer thickness in cold environment (Barton Peninsula, Antarctica) (Kim et al, 2020). Additionally, the snowmelt from a seasonal snowpack or ice and its isotopic (δ 18 O and δD) variation are important parameters for studying the snowmelt hydrology, particularly for the accurate hydrograph separation of spring runoff (Taylor et al, 2002;Lee et al, 2010;Lee, 2014a;Kim et al, 2017;Ham et al, 2019).…”

Soil moisture is an important variable for understanding hydrological processes, and the year-round monitoring of soil moisture and temperature reflect the variations induced by snow cover and its melt. Herein, we monitored the soil moisture and temperature in high (two sites) and low (two sites) elevation regions with groundwater sampling near the Mt. Balwang area in Gangwon-do, South Korea from Sep 2020 to May 2021. This study aims to investigate the temporal and spatial variations in soil moisture and temperature due to snow (natural and artificial snow) and its melt. A ski resort has been operating in this area and has been producing artificial snow during winter periods; thus, the spring snowmelt comprises both natural and artificial snow. The effect of soil freezing and thawing, wind conditions, vegetation covers, the timing and intensity of snow cover and snowmelt were differed in the monitoring sites. The high elevation sites 1 and 2 exhibit the relatively longer and consistent snow cover than the low elevation sites. Particularly, site 2 show late (May 8) snow melting even this site is in south slope of the Mt. Balwang. The relatively steady and moist soil layers at sites 1, 2, and 3 during the warm period can be considered as influential points to groundwater recharge. Moreover, the differences between the mean δ18O (−9.89‰) of the artificial snow layers and other samples were low: in the order of surface water (0.04‰) >groundwater (−0.66 and −1.01‰) >natural snow (1.34 and −3.80‰). This indicates that the imprint of artificial snow derived from surface water and with decreasing amount of natural snow around the Mt. Balwang region, the results support the assumption that the potential influence of artificial snowmelt on groundwater quality. This study helps to understand the snow dynamic and its influence on the hydrological processes in this region by combining the hydro-chemical and isotopic analysis.
